Among the following the one that gives positive iodoform test upon reaction with ` I _ 2 and NaOH ` is \

Options

A. `CH_(3)CH_(2)Ch(OH)CH_(2)CH_(3)`
B. `C_(6)H_(5)CH_(2)CH_(2)OH`
C. `CH_(3)-underset(CH_(2)-OH)underset(|)(CH)-CH_(3)`
D. `PhCHOHCH_(3)`

Answer

D

Explanation

For positive iodoform test, alcohol molecules must have `CH_(3)-underset(OH)underset(|)(CH)-` group
`Ph-underset(OH)underset(|)(CH)-CH_(3)overset(I_(2)+NAOH)rarrCHI_(3)+Ph-COO^(-)`.
