Question

Which one of the following is least basic? (A) NF3 (B) NCl3 (C) NBr3 (D) NI3

Tardigrade Admin · Accepted Answer

NF3 has least tendency to donate a pair of electrons (basicity) because of high electronegativity of F. The Lewis base strength of the other trihalides increases as the electronegativity of halogen decreases.

Q. Which one of the following is least basic?

$N F_{3}$

$NC l_{3}$

$NB r_{3}$

$N I_{3}$

$N F_{3}$ has least tendency to donate a pair of electrons (basicity) because of high electronegativity of $F$ . The Lewis base strength of the other trihalides increases as the electronegativity of halogen decreases.
