Question

$H_{2}O$ boils at higher temperature than $H_{2}S$, because it is capable of forming:

• A. ionic bonds
• B. covalent bonds
• C. hydrogen bonds
• D. metallic bonds

Answer 1

The correct option is C hydrogen bonds

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. Because of hydrogen bonding in $H_{2}O$, it boils at a temperature higher than $H_{2}S$.
