Question

Which is the volatile covalent liquid at ${25}^{\circ }\text{C}$ and 1 atm ?

• A. N${}_2$
• B. Kl
• C. CCl${}_4$
• D. AgNO${}_3$
• E. CaCO${}_3$

Answer 1

Answer: (C)

CCl${}_4$

Usually, compounds comprising of only non-metals tend to have covalent bonds. Therefore, among the given options, only A and C are covalent compounds. However, between the two, $N_2$ exists as a gas. $CC{l}_4$ is a covalent compound that exists as a liquid at standard temperature and pressure.
