(CH_(3))_(3)C-OCH_(3) on reaction with HI gives (CH_(3))_(3)C-I and CH_(3)-OH as the main products and not (CH_(3))_(3)C-OH and CH_(3)-I . Explain.

Give reasons for 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) (CH)(3))_(2)C-O-CH_(3) on reaction with HI gives (CH_(3))_(3)C-I andCH_(3)-OH as the main products and not (CH_(3))_(3)C-OH and CH_(3)-I .
