Choose the incorrect statement from the following.In case of primary, secondary and tertiary amines, the basic strength depends on the extent of hydrogen bonding in the protonated amines.The presence of groups like −OCH3 and −CH3 increases the basic strength of amines.The presence of groups like −NO2, CN and halogens reduces the basic strength of amines.The basic strength of amines depends on their concentration.
Question
Choose the incorrect statement from the following.In case of primary, secondary and tertiary amines, the basic strength depends on the extent of hydrogen bonding in the protonated amines.The presence of groups like −OCH3 and −CH3 increases the basic strength of amines.The presence of groups like −NO2, CN and halogens reduces the basic strength of amines.The basic strength of amines depends on their concentration.
Solution
The incorrect statement is: "The basic strength of amines depends on their concentration."
The basicity of amines does not depend on their concentration. Instead, it depends on the electronic configuration, the inductive effect, the resonance effect, and the solvation effect. The presence of electron-donating groups increases the basic strength of amines, while the presence of electron-withdrawing groups decreases their basic strength.
