Number of isomeric alcohols of molecular formula C6H14O which give positive iodoform test is

1. two
2. three
3. four
4. five

Correct answer: three

Solution

The iodoform test is given by alcohols with the structure R-CH(OH)-CH3. For C6H14O, three such isomeric alcohols can be formed: 2-pentanol, 3-methyl-2-butanol, and 2-methyl-2-pentanol.
