Among the following the one that gives positive iodoform test upon reaction with I_(2) and NaOH is ?

Answer»

`CH_(3)CH_(2)Ch(OH)CH_(2)CH_(3)`
`C_(6)H_(5)CH_(2)CH_(2)OH`
`CH_(3)-underset(CH_(2)-OH)underset(|)(CH)-CH_(3)`
`PhCHOHCH_(3)`

SOLUTION :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^(-)`.
