Addition of alcohols to aldehydes and ketones takes place in presence of dry gas because it
(i) Protonates the oxygen of the carbonyl compounds
(ii) Increases the electrophilicity of the carbonyl carbon
(iii) Removes the excess moisture from the reaction
(iv) Helps the reaction to move in the forward direction
(i) Protonates the oxygen of the carbonyl compounds
(ii) Increases the electrophilicity of the carbonyl carbon
(iii) Removes the excess moisture from the reaction
(iv) Helps the reaction to move in the forward direction
View answer and explanation
Correct option: B
(i), (ii), (iii) and (iv)
Option B ((i), (ii), (iii) and (iv)) is correct because dry HCl protonates the carbonyl oxygen, increases the electrophilicity of the carbonyl carbon, removes excess moisture, and helps the reaction move forward.
