The correct order of the basic strength of methyl substituted amines in aqueous solution is :

  1. (CH3)3N > (CH3)2NH > CH3NH2
  2. CH3NH2 > (CH3)2NH > (CH3)3N

Ques. 11NEET 2018

Nitration of aniline in strong acidic medium also gives m-nitroaniline because

  1. in spite of substituents nitro group always goes to only m-position
  2. in electrophilic substitution reactions amino group is meta directive
  3. in absence of substituents nitro group always goes to m-position
  4. in acidic (strong) medium aniline is present as anilinium ion
