Question

Account for the foloowing -

1) CH3CHO is more reactive than CH3COCH3 towards reaction with HCn? reason..

2) Carboxilic acid is stronger than phenol.. reason

Answer 1

2. 2 OH bond thats why more stronger.

Answer 2

Hey !!

1) CH₃CHO is more reactive than CH₃COCH₃ towards reaction with HCN because the positive charge on carbonyl carbon of CH₃CHO decreases to a  lesser extent due to one electron releasing ( +I effect ) CH₃ group as compared to CH₃COCH₃ ( two electrons releasing CH₃ group ) and hence more reactive.

2)  Carboxilic acid is stronger than phenol because carboxylate ion (conjugate base) is more resonance stabilized than phenoxide ion.

Good luck !!
