Question

In keto-enol tautomerism of dicarbonyl compounds the enol-form is preferred in contrast to the keto-form, this is due to (A) presence of carbonyl group on each side of - CH2 - group (B) resonance stabilisation of enol form (C) presence of methylene group (D) rapid chemical exchange

Resonance stabilisation of enol form as shown

Q. In keto-enol tautomerism of dicarbonyl compounds the enol-form is preferred in contrast to the keto-form, this is due to

presence of carbonyl group on each side of $- C H_{2} -$ group

resonance stabilisation of enol form

presence of methylene group

rapid chemical exchange

Resonance stabilisation of enol form as shown
