Acidic and basic nature of organic compound depends upon-Inductive effect. Acidic strength of organic acid increase with increase in electron withdrawing group or - group and decrease withincrease in electron releasing group or + group. Basic strength of organic compound having just opposite relationship with inductive effect, i.e. basic strength prop+1 effecte position of equilibrium of ionization in water. In other words acid strength is the function of the stability of conjugate base of the acid. More is the stability of conjugate base of the acid, more is the acidity of acid. Which one of the following is most acidic in character?
Amines are basic in nature due to the presence of lone pair of electrons on N atom of -NH_(2) group. The basic strength of amines can be expressed by their dissociation constant, K_(b) or pK_(b) . RNH_(2) + H_(2) to R NH_(3)^(+) + OH^(-) K_(b) = ([RHH_(3)^(+)][OH^(-)])/([RNH_(2)]) and pK_(b) = -log K_(b) Greater the K_(b) value or smaller the pK_(b) value, more is the basic strength of amine. Aliphatic amines are stronger bases than ammonia due to the electron releasing effect of alkyl groups. The basic strength among amines decreases as : 2^(@) gt 1^(@) gt 3^(@) Aryl amines such as aniline are less basic than aliphatic amines due to the involvement of lone pair of electrons on N atom with the resonance in benzene. In derivatives of aniline, the electron releasing groups increase the basic strength while electron withdrawing groups decrease the basic strength. The base weakening effect of electron withdrawing group and base strengthening effect of electron releasing group is more marked at p-position than at m-position. Every o- substituted aniline is less basic than aniline due to ortho effect. The strongest base among the following is
