Question

Which among the following is liquid at room temp. ? 

(a) Methyl chloride 

(b) Methyl bromide 

(c) Ethyl chloride 

(d) Dichloromethane

Answer 1

Among the given options, (d) Dichloromethane is liquid at room temperature. Dichloromethane, also known as methylene chloride, has a boiling point of 39.6°C and a melting point of -96.7°C, making it a liquid at room temperature.

Answer 2

At room temperature (approximately 25°C or 77°F), only Dichloromethane (CH2Cl2) is a liquid among the options given.

Dichloromethane is liquid at room temperature. Therefore, option (d) is the correct answer.

Methyl chloride (CH3Cl), Methyl bromide (CH3Br), and Ethyl chloride (C2H5Cl) are all gases at room temperature.
