$C-H \cdots O$

Vedclass · Answer

(A) The strength of a hydrogen bond $X-H \cdots Y$ depends on the electronegativity difference between $X$ and $H$. As the electronegativity of $X$ decreases, the polarity of the $X-H$ bond decreases, resulting in a smaller partial positive charge $(\delta+)$ on the hydrogen atom. This leads to a weaker electrostatic attraction between the hydrogen atom and the electronegative atom $Y$. The electronegativity values are $C (2.5) Therefore, the $C-H \cdots O$ hydrogen bond is the weakest among the given options.

Which of the following hydrogen bonds is likely to be the weakest?
