Question

${\left(C{H}_3\right)}_4\stackrel{+}{N}$ is neither an electrophile, nor a nucleophile because it

• A. does not have electron pair for donation as well as cannot attract electron pair
• B. neither has electron pair available for donation nor can accommodate electron since all shells of nitrogen are fully occupied
• C. can act as Lewis acid and base
• D. none of these.

Answer 1

Answer: (B)

${\left(C{H}_3\right)}_4{N}^{+}$ has no electron pair available for donation to act as nucleophile. Valence shell of nitrogen is completely filled and has no scope for acceptance of extra electrons to act as electrophile.
