Question

Which of the following compound CANNOT act as a Lewis base? (A) NF 3 (B) PCl 5 (C) SF 4 (D) ClF 3

Tardigrade Admin · Accepted Answer

Lewis base: Chemical species which has capability to donate electron pair. In NF 3, SF 4, ClF 3 central atom (i.e. .N , S , Cl ) having lone pair therefore act as lewis base. In PCl 5 central atom (P) does not have lone pair therefore does not act as lewis base.

Q. Which of the following compound CANNOT act as a Lewis base?

$N F_{3}$

$PC l_{5}$

$S F_{4}$

$Cl F_{3}$

Lewis base : Chemical species which has capability to donate electron pair.

In $N F_{3}, S F_{4}, Cl F_{3}$ central atom (i.e. $N, S, Cl)$ having lone pair therefore act as lewis base.

In $PC l_{5}$ central atom $(P)$ does not have lone pair therefore does not act as lewis base.
