Question

Given the following electronegativity values:
H: 2.2 N: 3.0 O: 3.4 F: 4.0
Which bond has the greatest polarity?
A. O-H in H2O B. N-O in NO2
C. N-F in NF3 D. N-H in NH3

Answer 1

Answer:

Option (a) is correct.

Explanation:

1) The difference between electronegativities of O and H atoms is more. hence it is much polar compared to other molecules.
