Question

What is increasing strength of hydrogen bonding?

$(X...H-X)(X=O,S,F,Cl,N)$?

• A. $S<Cl<O<N<F$
• B. $S<N<Cl<O<F$
• C. $S<Cl<N<O<F$
• D. None of these

Answer 1

The correct option is C $S<Cl<N<O<F$

A hydrogen bond is the electrostatic attraction between polar groups that occurs when a hydrogen $\left(H\right)$ atom bound to a highly electronegative atom such as nitrogen $\left(N\right)$, oxygen $\left(O\right)$ or fluorine $\left(F\right)$ experiences attraction to some other nearby highly electronegative atom. More electronegative the element, more is the hydrogen bonding.

Hence, the order is $S<Cl<N<O<F$.
