What is the relative order of bond polarity, with respect to #N-H#, #O-H#, #F-H#, and #P-H#?

1 Answer

Answer:

#underbrace(H-P, H-N, H-O, H-F)_rarr#
#"Order of increasing bond polarity......"#

Explanation:

And how to assess this quantitatively? Well, examine the Pauling electronegativities of #H(2.02); P(2.19); N(3.04); O(3.44); F(3.98)#

Clearly, #H-F# should give rise to the most polar bond.
