Why is Aniline very reactive towards bromination ?Why is Aniline very reactive towards bromination ?
Asked by pratikbharadia | 10 Dec, 2009, 08:34: AM
answered-by-expert Expert Answer

This is because NH2 group in aniline is highly activating group. A lone pair of electrons is present on N which releases the electron density to the benzene ring and hence activates the benzene ring towards electrophilic substitution reactions at ortho and para positions.

Since in bromination, Br+ is the electrophile. So, aniline reacts with bromine water at room temperature to give a white precipitate of 2,4,6 - tribromoaniline.

sir/madam, this doubt will be lenghty. request peace reading. the doubt is w.r.t chapter Amines; to be specific it is w.r.t basicity of amines. in the topic of the comparision of the basic character of alkylamines with ammonia,  the order of basicity of amines is tertiary> secondary> primary in gaseous phase, only due to the +I effect. in gasous phase only +I effect is shown? also in the aqueous phase, the disturbancy in the order of basicity is due to the sum of effects of +I effect, solvation effect and steric hindrance? the order of the stability of the following in aqueous phase: +I effect: tertiary> secondary> primary solvation: primary > secondary > tertiary steric hindrance: primary > secondary > tertiary so does it means that +I is effected in both gaseous and aqueous phase but solvation and steric hindrance are effected only in aqueous phase? also sir there is an order of basicity when R= CH3 group and when R= C2H5 group: R= CH3: secondary> primary> tertiary R= C2H5: secondary> tertiary> primary so sir can we generalise the order that: when R=CH3 group, the order of basicity: secondary> primary> tertiary and when R> CH3 group, the order of basicity: secondary> tertiary> primary

sir/ madam, is it true that if no of bonds in an atom increases then the atom acquires a positive charge on it and when it loses one bond it acquires a negative charge on it ? why does it happen so?
