Acrolein test is positive for
- A polysaccharides
- B proteins
- C oils and fats
- D reducing sugars
Answer & Solution
Correct Answer
(C) oils and fats
Step-by-step Solution
Detailed explanation
Acrolein test is positive for oils and fats when fat is heated in presence of \(\mathrm{KHSO}_{4}\), the glycerol portion of molecule is dehydrated and form unsaturated aldehyde. \(\mathrm{CH}_{2}=\mathrm{CH}-\mathrm{CHO}\) (acrolein) a bad smelling compound.
