Vedclass · Accepted Answer

$C_6H_5OH$ is more acidic than $C_2H_5OH$

Vedclass · Answer

(A) The acidity of $C_6H_5OH$ (phenol) is greater than that of $C_2H_5OH$ (ethanol) because the phenoxide ion formed after the loss of $H^+$ is stabilized by resonance with the benzene ring,whereas the ethoxide ion $(C_2H_5O^-)$ is destabilized by the electron-donating inductive effect $(+I)$ of the ethyl group.Phenol does not react with $NaHCO_3$ because it is a weaker acid than carbonic acid $(H_2CO_3)$.Phenol does not react with $NH_2OH$ to form an oxime; this reaction is characteristic of carbonyl compounds (aldehydes and ketones).
