Question

Which of the following molecules will exhibit hydrogen bonding?

Answer 1

Answer:

B. HF

Explanation:

Hydrogen bonding is basically a bond between hydrogen and an electronegative element particularly the second-row elements nitrogen (N), oxygen (O), or fluorine (F).

option A.

Although oxygen is present, there are no  O - H bond present. The oxygen is bonded to two carbon atoms hence hydrogen bonding is absent.

option B.

Hydrogen is bonded directly to Flourine. Hydrogen bond is present.

option C.

This is an organic compound, only covalent bonds are present in this molecule. No hydrogen bonds,

option D.

Lithium does snot have high electronegativity hence hydrogen bonding is absent.
