Question

3.
O, F, N in order of increasing strength of hydrogen bonding (X---H-X) is
a) F<O<N
b) F>O<N
c) N>O>F
d) N<O<F
​

Answer 1

A hydrogen bond is the electrostatic attraction between polar groups that occurs when a hydrogen (H) atom bound to a highly electronegative atom such as nitrogen (N), oxygen (O) or fluorine (F) experiences attraction to some other nearby highly electronegative atom. More electronegative the element, more is the hydrogen bonding.

so, F>O>N

Answer 2

Answer:

d) N<O<F.

Explanation:

F is more electronegative than O. and O is more electronegative than N.
