MCQ
Which statement is not correct
  • A
    Amines form hydrogen bond
  • B
    Ethyl amine has higher boiling point than propane
  • C
    Methyl amine is more basic than ammonia
  • Dimethyl amine is less basic than methyl amine

Answer

Correct option: D.
Dimethyl amine is less basic than methyl amine
d
(d)In methyl amine only one electron releasing group is present but in dimethyl amine two electron releasing groups are present which increase the basicity higher in dienethyl amine.
