The carbon attached to this moiety will get the #1 location number in naming the ring. If the aldehyde moiety (-CHO) is attached to a ring the suffix –carbaldehyde is added to the name of the ring. When a metal element reacts with a non-metal element an ionic compound is formed. The atom adjacent to the carbonyl function is alpha, the next removed is beta and so on. GCSE Edexcel Ionic compounds - Edexcel Naming ionic compounds with -ide and -ate. the prefix (section at the beginning of the word) of the second element changes based on how many atoms there are in the compound. elements, the periodic table, reactions, and biochemistry. Other sections include matter, elements, the periodic table, reactions, and biochemistry. In common names of aldehydes, carbon atoms near the carbonyl group are often designated by Greek letters. This tutorial introduces compound naming in chemistry. For aldehydes common parent chain names, similar to those used for carboxylic acids, are used and the suffix –aldehydeis added to the end. There are several simple carbonyl containing compounds which have common names which are retained by IUPAC.Īlso, there is a common method for naming aldehydes and ketones. Since an aldehyde carbonyl group must always lie at the end of a carbon chain, it is always is given the #1 location position in numbering and it is not necessary to include it in the name.

These prefixes are Greek (mon-, di-, tri-, etc) and the last element in the formula also gets the suffix -ide.

For example, H 2C=O is methan al, more commonly called formaldehyde. In naming covalent compounds, each element in a covalent compounds needs a prefix to denote the number of atoms of that element. The IUPAC system of nomenclature assigns a characteristic suffix - al to aldehydes.
