3. CH3CH2CH2CH2CH2OH, i show this to be 1-Pentanol which is primary.
2 is 2-methyl butanol.
To find the IUPAC name of a compound and classify it as primary, secondary, or tertiary, you need to identify the longest continuous carbon chain and determine the type of carbon atom connected to the functional group.
1. CH3CH2-O-/..\
The longest continuous carbon chain is 2 carbons, so this is an ethyl group. The functional group is an alcohol (-OH) attached to the ethyl group. The IUPAC name for this compound is ethyl alcohol or ethanol. In terms of classification, the carbon attached to the -OH group is a primary carbon, as it is directly connected to one other carbon.
2. CH3
.......\
.......CH-CH2-CH2-OH
......./
....CH3
The longest continuous carbon chain is 3 carbons, so this is a propyl group. The functional group is an alcohol (-OH) attached to the last carbon atom of the propyl group. The IUPAC name for this compound is 1-propanol. In terms of classification, the carbon attached to the -OH group is a secondary carbon, as it is directly connected to two other carbon atoms.
3. CH3CH2CH2CH2CH2OH
The longest continuous carbon chain is 5 carbons, so this is a pentyl group. The functional group is an alcohol (-OH) attached to the last carbon atom of the pentyl group. The IUPAC name for this compound is 1-pentanol. In terms of classification, the carbon attached to the -OH group is a primary carbon, as it is directly connected to one other carbon.
