Steps in Naming Branched Alkanes Step 1: Count the number of carbon atoms in the longest chain and name the chain. Step 2: Number the carbon atoms from the end where a branched group has the lowest numbered carbon atom. Step 3: Count the number of carbon atoms in each branch and name each branch.

The Basic Rules for Naming Alkenes Find the longest carbon chain that contains both carbons of the double bond. Start numbering from the end of the parent chain which gives the lowest possible number to the double bond. ... Place the location number of the double bond directly before the parent name.

IUPAC Rules for Alkane Nomenclature Find and name the longest continuous carbon chain. Identify and name groups attached to this chain. Number the chain consecutively, starting at the end nearest a substituent group. Designate the location of each substituent group by an appropriate number and name.

An alkane with alkyl groups linked to its main carbon chain is a branched-chain alkane or branched alkane. Branched alkanes include carbon and hydrogen (C and H) atoms, and carbon atoms are only coupled to certain other carbons by single bonds.

Naming of Isomers ing to the IUPAC Nomenclature There are three parts in the naming of isomers: Prefix indicated by the branch group, which is alkyl group, attached to the longest carbon chain. The root name showing the number of carbon atoms in the longest carbon chain. The suffix showing the homologous series.

For alkanes suffix '-ane' is used, for alkenes, the suffix '-ene' is used and the suffix 'yne' is used for alkynes. For example, C2H6 is known as ethane, C2H4 is known as ethene and C2H2 is known as ethyne.
