Question

name the two conditions which must be satisfied for hydrogen bonding to take place in a molecule ?​

Answer 1

Answer:

1. The molecule should contain a highly electronegative atom linked to H-atom.

2. The size of the electronegative atom should be small.

Answer 2

"Hydrogen bonding" is a sort of partial "electrostatic force" of "attraction". For "hydrogen bonding" to take place in a "molecule", two conditions that are to be satisfied are

(i) Highly electronegative atom with small size (F, O, and N) must be present in the molecule and hydrogen atom should be covalently bonded to it. They are hydrogen bond donors.

(ii) Another adjacent atom which is highly electronegative should have a "lone pair of electrons". They are hydrogen bond acceptors."
