Question

If the boiling point of H₂O is 373 K, the boiling point of H₂S will be ______.

Options

• equal to 373 K.

• greater than 300 K but less than 373 K.

• less than 300 K.

• more than 373 K.

Answer 1

If the boiling point of H₂O is 373 K, the boiling point of H₂S will be less than 300 K.

Explanation:

Water has a high boiling point due to strong hydrogen bonding between its molecules, whereas H₂S lacks hydrogen bonding and has weaker intermolecular forces, so it boils at a much lower temperature, around 213 K.
