Question

The molar masses of C, H, A, CHOH, and CHF are very similar. How do their boiling points compare?

• A. \( C_2H_6<CH_3OH<CH_3F \)
• B. \( CH_3F<CH_3OH<C_2H_6 \)
• C. \( CH_3OH<C_2H_6 \)
• D. \( C_2H_6<CH_3OH<CHF_3 \)

Hint:

Intermolecular forces like hydrogen bonding increase the boiling point of molecules.

Answer 1

The Correct Option is D

Boiling points depend on intermolecular forces. \(CH_3OH\) has hydrogen bonding, which raises its boiling point compared to \(C_2H_6\) and \(CHF_3\), which have weaker forces.
