Question

Name the two conditions which must be satisfied for hydrogen bonding to take place in a molecule.

Answer 1

""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."

Answer 2

HEYA MATE.....
HERE IS THE ANSWER .....


1. A BOND MUST BE COVALENT WITH HYDROGEN.

2. A ELEMENT MUST BE ELECTRONEGATIVE

3. A MUST BE F,O,N.

4. B ELEMENT MUST BE LITTLE ELECTRONEGATIVE.

5. B MUST BE STRICTLY F,O,N.

6. B MUST HAVE LONE PAIR.




I HOPE IT IS HELPFUL....☺✌☺
