Question

39. Which bond is least polar?
A) As-C1
B) Bi-CI
C) P-CI
D) N-C1

Answer 1

Answer:

D) N-Cl.

Explanation:

The electronegativity of the elements in Group 5 (N. P As and Bi) decreases as we go down the Group so N is the most electronegative and chlorine is less able to draw electrons away from N than from the other elements in Group 5.
