MCQ
Which of the following compounds is most basic ?
  • A


  • C

  • D

Answer

Correct option: B.

b
The compound is most basic due to localised lone pair of electrons on nitrogen atom while in other compounds, as result of resonance, the lone pair of electrons on nitrogen atoms gets delocalised over benzene ring and thus is less easily available for donation.
