Fehling's solution can make distinction ...

Fehling's solution can make distinction between:

A

`MeCHO and PhCHO`

B

`MeCHO` and `CH_(3)-underset(O)underset(||)C-CH_(2)OH`

C

`H_(3)C-underset(OH)underset(|)CH-underset(O)underset(||)C-CH_(3)` and `HCHO`

D

`MeCHO and HCHO`

Text Solution

Verified by Experts

The correct Answer is:
A
a. Fehling's solution reacts only with aliphatic aldehyde, not with aromatic aldehyde.
b. F.S. reacts with MeCHO and also with alpha-hydroxy ketones

c. F.S. reacts with both HCHO and with alpha-hydroxy ketone

d. F.S. reacts with both aliphatic aldehydes (MeCHO and HCHO). So the answer is `(a)`.
