Which is the most suitable reagent for the following conversion ?
`CH_(3)-CH=CH-CH_(2)-overset(O)overset(||)(C)-CH_(3)to`
`CH_(3)-CH=CH-CH_(2)-overset(O)overset(||)(C)-OH`

Options

A. Tollen's reagent
B. Benzoyl peroxide
C. `I_(2)" and "NaOH` solution
D. `Sn" and "NaOH` solution

Answer

C

Explanation

Iodoform test is used to test presence of `-COCH_(3)` group which is converted into `-COOH` group.
The reaction is shown as
`CH_(3)-CHunderset("Hex-4-en-2-one")underset()(=CH-CH_(2)-overset(O)overset(||)C-CH_(3))overset(I_(2)//"NaOH solution")underset("Iodoform reaction")rarrCH_(3)-CH=underset("Pent-3-en-1-oic acid")underset()(CH-CH_(2))-overset(O)overset(||)C-OH`
