Question

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
The correct order​

Answer 1

Answer :

★ Hydrogen bond : The attractive force which binds hydrogen atom of one molecule with the electronegative atom (F, O or N) of another molecule is called Hydrogen bond$.$

• Strength of hydrogen bond depends on the electronegativity of bonded atom.

★ The tendency of an atom in a chemical compound to attract shared pair of electrons to itself is called electronegativity.

Order of EN : N < O < F

Order of strength of H-bond :

• N < O < F

Hence, (D) is the correct answer.
