Question

Which of the following compounds exhibits H-bonding?

$C{H}_{3}C{H}_{2}OH$ and $C{H}_{3}OC{H}_3$

• A. $C{H}_{3}C{H}_{2}OH$
• B. $C{H}_{3}OC{H}_3$
• C. Both
• D. None

Answer 1

The correct option is A $C{H}_{3}C{H}_{2}OH$

A hydrogen bond is the electrostatic attraction between polar groups that occurs when a hydrogen ($H$) 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. The presence of $OH$ group in ethanol leads to hydrogen bonding.
