What is the strength of a hydrogen bond determined by?

A $Interaction between the lone-pair electrons of the electronegative atom of one molecule and the hydrogen atom of another molecule$
B $Interaction between the lone-pair electrons of the electropositive atom of one molecule and the hydrogen atom of another molecule$
C $Interaction between the lone-pair electrons of the electronegative atom of one molecule and the oxygen atom of another molecule$
D $Interaction between the lone-pair electrons of the polar molecule and the hydrogen atom of another molecule$

Solution & Step-by-step Explanation

A hydrogen bond is an attractive electrostatic interaction between a hydrogen atom covalently bonded to a highly electronegative atom (like N, O, or F) and the lone-pair electrons of an electronegative atom of an adjacent molecule. The strength is determined by the alignment and magnitude of this electrostatic sharing.

Try it yourself before checking the explanation above.
