(a)
Interpretation:
The stronger base in the given pair of amine compounds should be determined.
Concept introduction:
Due to ability of lone pair in the nitrogen atom to accept a proton, amines are weak base in nature.
Factors that affect the basicity of amines are listed below,
Substitution by alkyl groups
The presence of alkyl groups (electron donating group) such as
Substitution by electron-withdrawing groups
The presence of electron-withdrawing groups or atom will decrease the basicity.
(b)
Interpretation:
The stronger base in the given pair of amine compounds should be determined.
Concept introduction:
Amines are the derivatives of ammonia
Due to ability of lone pair in the nitrogen atom to accept a proton, amines are weak base in nature.
Factors that affect the basicity of amines are listed below,
Substitution by alkyl groups
The presence of alkyl groups (electron donating group) such as
Substitution by electron-withdrawing groups
The presence of electron-withdrawing groups or atom will decrease the basicity.
