Acrolein test is positive for

A

polysaccharides

B

proteins

C

oils and fats

D

reducing sugars

Text Solution

Verified by Experts

The correct Answer is:
C
When a fat is heated strongly in the presence of a dehydrating agent such as `KHSO_(4)`, the glycerol portion of the molecule is dehydrated to form the unsaturated aldehyde acrolein, `CH_(2)=CHCHO`, which has the peculiar odour of burnt grease. This is the standard test for fats.
