There is a propyl substituent on the inside double bond carbon atom (#2), so the IUPAC name is: 2-propyl-1-pentene. When we name compounds, the names of the elements in the compound are combined and sometimes changed slightly, to make a name for the compound. Dodecahedrane: A Platonic hydrocarbon shaped like a dodecahedron. There’s a better option out there! Basketane (pentacyclo[4.4.0.0 2,5.0 3,8.0 4,7]decane) (C 10 H 12), a polycyclic alkane with a structure similar to a basket. For starters, the nonmetal element should have the end of its name replaced with the suffix -ide. Updated: Oct 8, … Since Ca is not an alkali metal, the compound Ca3(PO4)2 is insoluble in water and will precipitate out of solution as a solid. Not quite! ", "Helped with planning a middle school chemistry section. For example, sulfate SO, Example: NaOH. Back to Science for Kids Introductory Chemistry Online/Chemical Bonding and Nomenclature. Rule 4 : Give the root name Root name of the compound can be given by counting the number of carbons in the parent chain. Learning to name ionic compounds is both easy and hard depending on the complexity of the compound. AAA's advice about warming up your car when it's cold out. This is something you need to master before naming or writing chemical formulas. IUPAC names can be generated for drawn structures in the sketcher. Bess Ruff is a Geography PhD student at Florida State University. The first word is the name of the first element. We've been helping billions of people around the world continue to learn, adapt, grow, and thrive for over a decade. Ionic compounds occur between metals and non-metals. Follow this guide for some basic rules on how chemical compounds get their name, and how to apply names to compounds you are unfamiliar with. An anhydride is a hydrate that has lost water. Does the formula begin with an h. Fluorine fluoride. Nope! These groups must, of course, always be attached to something else. A functional groupis a specific group of molecules you can easily spot in a compound. Yes! Approved. For this compound the functional group alkane (C-H atom) is present, so take a look at the t… There’s a better option out there! Donate Login Sign up. If you're behind a web filter, please make sure that the domains *.kastatic.org and *.kasandbox.org are unblocked. Every dollar contributed enables us to keep providing high-quality how-to help to people like you. You have to memorize the common polyatomic compounds, like chromate ion and others. The process of naming compounds is just a set of rules. Basic Naming Convention First we'll cover how to name molecules with two elements (binary compounds). Naming Ionic Compounds Using -ite and -ate Some polyatomic anions contain oxygen. The Benzene Ring. Names written according to a method of organic compounds are called their IUPAC names. Naming basic chemical compounds is essential if you want to succeed in chemistry, since the name of the compound clearly defines what it is. PO4 is already called phosphate. If you remove a hydrogen atom from one of these you get an alkyl group. For example, “carbonate” CO, Remove an oxygen from the compound. A comparison table for IUPAC naming against two of our competitors is provided below. Often, more than one name is acceptable and it's not uncommon to find the old names still in use as well. A prefix or a suffix generally has a specific meaning that it denotes - like the prefixes in Method 3 Step 2, which indicate the number of atoms. By using our site, you agree to our. When a compound has an oxygen removed or added, it changes into either an -ite or -ate compound. Why is the mono not said in CO, like monocarbon monoxide? ", "I would like to thank wikiHow for helping me out in my queries about how to name ionic compounds. What is the difference between ionic compounds and covalent compounds? wikiHow marks an article as reader-approved once it receives enough positive feedback. All aromatic compounds are based on benzene, C 6 H 6, which has a ring of six carbon atoms and has the symbol: Each corner of the hexagon has a carbon atom with a … To learn how to name polyatomic compounds, read on! Refer to the periodic table of elements to see what categories the elements in the compound belong to. Cubane: A hydrocarbon whose eight carbon atoms occupy the vertices of a cube. For example when there are 2 atoms use the prefix di and before naming the rest of the compound. Covalent compounds are molecules formed by non-metals bonded together by sharing electrons.. Covalent compounds are named by using numerical prefixes to identify the number of atoms in the molecule.. For example Carbon Dioxide #CO_2# and Carbon Monoxide #CO#. For example: NO, Replace the central atom with another from the same periodic group. But, why is it chloride and not chlorine? When an element forms two oxyanions, the one with less oxygen is given a name ending in -ite and the one with more oxygen are given a name that ends in -ate. Definitely not! Include your email address to get a message when this question is answered. Most PO43− compounds are insoluble in water, with exceptions being the alkali metals (group 1 on the periodic table), and the ammonium cation, NH4 . Read more. By using this service, some information may be shared with YouTube. Consequently, the root name of this compound will be pentene. How do I identify elements of a compound that ends with -ate? A charge of four is represented by the prefix tetra-. For example, how do I know that carbonate is comprised of 1 Carbon and 3 oxygen atoms? It is still used for carbon monoxide due to the term being in use since early chemistry. The names of ionic compounds aren’t simply the names of both elements combined together without any change. About this quiz: All the questions on this quiz are based on information that can be found at Chemistry: Naming Compounds. Not quite! References A charge of 1 is represented by the prefix mono-, but chlorine here has a charge of 4. Most crucially, be sure to replace the end of the name of the nonmetal element with the suffix -ide. Coordination compounds contain an ion and an array of ligands. PO4 has an oxygen removed from the compound. The name of a compound with two elements has two words. But now I can solve every problem very easily. Naming a compound with more than one functional group is not as straightforward as it is for alkanes, alkyl halides or alkenes. When naming covalent compounds, a charge of 1 is represented by the prefix mono-, but carbon here has a charge of 3. For example, NaF is also known as sodium fluoride. With the names of covalent compounds, a charge of 4 is represented by the prefix tetra, but carbon here has a charge of 3. Nope! This article was co-authored by Bess Ruff, MA. Please give it a try and let us know if you encounter any issues. How to name type II bonds: Follow the steps for type I and identify the compound with a roman numeral based on the oxodization level of the cation. Naming simple compounds. % of people told us that this article helped them. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/7\/7a\/Name-Chemical-Compounds-Step-1.jpg\/v4-460px-Name-Chemical-Compounds-Step-1.jpg","bigUrl":"\/images\/thumb\/7\/7a\/Name-Chemical-Compounds-Step-1.jpg\/aid1286499-v4-728px-Name-Chemical-Compounds-Step-1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"
