Question

what happens when glycerol is heated with KHSO4? Give equation.

Answer 1

CH2OH - KHSO4 (-2H2O) -> CH2=C=CH-OH - Tautomerize -> CH2=CH-CH=O (Acrolein also called acraldehyde)

Answer 2

Answer:

Results in formation of unsaturated aldehyde that is acrylic aldehyde.

Explanation:

Glycerol on heating potassium hydrogen sulfate , undergoes dehydration with removal of two water molecule from the the glycerol molecule. Hence, resulting in formation of unsaturated aldehyde that is acrylic aldehyde.

$CH_2(OH)-CH(OH)-CH_2(OH)+KHSO_4\overset{\Delta }\rightarrow CH_2=CH-CHO+2H_2O$
