The number of chiral alcohol(s) with molecular formula

C_{4} H_{10} O

is ____.

Answer: 1

Solution

The possible alcohols with molecular formula

C_{4} H_{10} O

are: 1-butanol (no chiral center), 2-butanol (one chiral center at C-2), isobutanol/2-methyl-1-propanol (no chiral center), and tert-butanol (no chiral center). Only 2-butanol (

CH_{3} CH (OH) CH_{2} CH_{3}

) has a chiral carbon atom. Therefore, the answer is 1.
