Question

Assertion H2O is a liquid and H2S is a gas___________Reason water molecule are held by h bond while in H2S molecule no such interaction are present between molecules​

Answer 1

$\[{H_2}O\]$ is a liquid and $\[{H_2}S\]$ is a gas. Water molecules are held by H-bond while in $\[{H_2}S\]$ molecules, no such interactions are present between molecules​. Thus, both assertion and reason are correct and the reason is the correct explanation of the assertion.

Explanation:

• In water ($\[{H_2}O\]$), the molecules are held together by hydrogen bonds.
• Hydrogen bonds are stronger than other types of interactions like Vanderwaal's interaction, dipole-dipole interaction, etc.
• These hydrogen bonds are not present in $\[{H_2}S\]$.
• Therefore, $\[{H_2}S\]$ is a gas while $\[{H_2}O\]$ is a liquid.
