Hint- In order to solve this problem first we will see the structure of isopropyl alcohol and some other iso and neo alcohols. On the basis of their structure and comparison we will select the correct option amongst the given options.
Complete answer:
The structure of isopropyl alcohol is:
Here the alcohol group is attached with the second carbon in the chain so this structure is secondary or ${2^0}$ structure.
Now let us see some other iso and neo alcohol
The figure given above is neopentyl alcohol, even if the alcohol group is attached to any of the carbon of neopentyl it will always be the first carbon or the edge carbon. So the structure will always be ${1^0}$ or primary structure.
The figure given above is iso-butyl alcohol, even if the alcohol group is attached to any of the carbon of iso-but it will always be the first carbon or the edge carbon. So the structure will always be ${1^0}$ or primary structure.
Similar will be the results for other iso and neo alcohol as well.
Hence, on the basis of these results we conclude that:
Except for isopropyl alcohol all iso and neo alcohols are primary alcohol.
So, option A is the correct option.
Note- The prefix "iso" is used when all carbons except one form a continuous chain. The "neo" suffix is used where all but two carbons form a continuous line, and those two carbons are part of a tert-butyl group of terminals. A primary alcohol is an alcohol in which a single carbon atom is bound to the hydroxyl groups. It can also be defined as a molecule containing a $ - C{H_2}OH$ group. In contrast, a secondary alcohol has a formula $ - CHROH$ and a tertiary alcohol has a formula $ - C{R_2}OH$ , where “R” indicates a carbon-containing group.
