Methyl chloride: Methyl chloride (CH3Cl) is a haloalkane that exists as a gas at room temperature. It has a boiling point of -23.7°C and a melting point of -97.7°C. Therefore, it does not exist as a liquid at room temperature.

Methyl bromide: Methyl bromide (CH3Br) is also a haloalkane that exists as a gas at room temperature. It has a boiling point of 3.5°C and a melting point of -93.7°C. Similar to methyl chloride, it does not exist as a liquid at room temperature.

Ethyl chloride: Ethyl chloride (C2H5Cl) is a haloalkane that exists as a liquid at room temperature. It has a boiling point of 12.3°C and a melting point of -138.7°C. Therefore, it satisfies the given condition and exists as a liquid at room temperature.

Propyl bromide: Propyl bromide (C3H7Br) is another haloalkane that exists as a liquid at room temperature. It has a boiling point of 71.5°C and a melting point of -111.2°C. Hence, it also satisfies the given condition and exists as a liquid at room temperature.

Conclusion: Among the given options, only ethyl chloride and propyl bromide exist as liquids at room temperature. Methyl chloride and methyl bromide exist as gases.
