Statement-1: -Methoxybenzaldehyde undergoes nucleophilic addition more readily than -nitrobenzaldehyde.
Statement-2: The carbon atom of the aldehyde group is more electrophilic in -nitrobenzaldehyde than in -Methoxybenzaldehyde.
Statement-2: The carbon atom of the aldehyde group is more electrophilic in -nitrobenzaldehyde than in -Methoxybenzaldehyde.
View answer and explanation
Correct option: D
Statement-1 is False; Statement-2 is True
Option D (Statement-1 is False; Statement-2 is True) is correct because electron-withdrawing groups increase the electrophilicity of the carbonyl carbon, making nucleophilic addition more favorable.

By passing water gas through an electric discharge at low pressure, we get:
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 Benzyl alcohol and sodium benzoate is obtained by the action of sodium hydroxide on benzaldehyde. This reaction is known as Which one of the following reactions is a condensation reaction? Carboxylic acids dimerise due to The number of aldehyde isomers for will be
