An optically active compound A `(C_6 H_(12 )O) `gives positive test with 2,4-D NP, but negative test with Tollen's reagent. Compound A is

A

B

`CH_3-CO-CH (CH_3)_2`

C

D

`CH_3CH_2 CO (CH (CH_3)_2`

Text Solution

Verified by Experts

The correct Answer is:
C
`A (C_6 H_(12) O)` gives positive test with ` 2,4 -DNP implies` Aldehyde or ketone
Negative test Tollen.s test `implies ` Ketone `CH_3 - underset(O ) underset(||)C- overset(CH_3) overset(|) CH-CH_2-CH_3`
