The general rule for the IUPAC nomenclature of an alkane and cyloalkane:
1. Find the longest carbon chain that contains the maximum number of carbon atom in a straight chain.
2. Number of Carbon atom is given by Greek prefixes like meth, eth, prop, but pent etc.
3. For saturated compound use ‘ane’ suffix
4. Start the number of carbon chain to that end where a substitute got minimum number.
5. Give the location and name for every substituent’s in alphabetically order as the prefix of the parent carbon chain.
6. For the cyclo-alkane use cyclo as prefix.
In the I.U.P.A.C. Nomenclature System, alcohols are named according to the following set of rules:
(i) Determine the parent compound, the longest continuous carbon chain bearing the –OH group.
(ii) Number the chain so that the –OH –-OH group has lowest number.
(iii) Replace the –e ending of the parent alkane with the suffix-ol . If there are two alcoholic groups, the suffix –diol acid is used.
(iv) Name and number substituents in the usual way.
The general rule for the IUPAC nomenclature of an alkyne and cyloalkyne:
1. Find the longest carbon chain that contains the maximum number of carbon atom in a straight chain.
2. Number of Carbon atom is given by Greek prefixes like meth, eth, prop, but pent etc.
3. For saturated compound use ‘ane’ suffix.
4. For double bond use ene and for triple bond use yne suffix.
5. Start the number of carbon chain to that end where a substitute got minimum number.
6. Give the location and name for every substituent’s in alphabetically order as the prefix of the parent carbon chain.
7. For the cyclo-alkane use cyclo as prefix.
