-1- Phenoxide ion is more stabilized than -x2212-CH3O ion through resonance- Thus- phenol is more acidic than methanol-2- Due to extensive intermolecular H-bonding the -x2212-C-x2212-O-x2212-H bond angle in alcohol slightly less than tetrahedral angle- H-bond thrust the angle slightly-3- Since- -CH-3C- is more stabilized through -I effect of three methyl group thus -CH3-3C-x2212-I and CH3OH formed on treatment of HI with -x2212-CH3-3-x2212-CO-x2212-CH3-MeC-x2212-O-x2212-Me-x2192-Me3C-MeO-x2212-HI-x2192-Me3C-x2212-I-MeOH

Give reasons of the following.(i) Phenol is more acidic than methanol. (ii) The C-O-H bond angle in alcohols is slightly less than the tetrahedral angle (109∘28′).(iii) (CH3)3C−O−CH3 on reaction with HI gives (CH3)3C−IandCH3−OH as the main products and not (CH3)3C−OHandCH3−I.
