The `IUPAC` name of neohexyl alcohol is

Options

A. `3,3-`dimethylbutan`-1-`ol
B. `3,3-`dimethylbutan`-2-`ol
C. `1,1-`dimethylbutan`-1-`ol
D. `2,2-`dimethylbutan`-1-`ol

Answer

A

Explanation

The longest carbon chain to which the hydroxyl group is bonded gives us the base name. The ending is `-ol` . We then number the longest chain from on end that gives the carbon bearing the hydroxyl group the lower number.
The prefix ' neo' signifies the presence of a quaternary carbon atom:
`H_(3)overset(4)(C) - underset(3,3-"Dimethylbutane"-1-ol)(underset(CH_(3))underset(|)overset(OH)overset(|3)C-overset(2)(CH_(2))overset(1)(CH_(2))overset(1)(CH_(2))OH`
