Question

Which of the following is volatile covalent liquid at room temperature ($25{}^{o}C$) and 1 atm?

• A. $N_2$
• B. $KI$
• C. $C{Cl}_4$
• D. $AgN{O}_3$
• E. $CaC{O}_3$

Answer 1

Answer: (C)

$C{Cl}_4$

Carbon tetrachloride is a colourless volatile non-flammable liquid with a characteristic odour, has:
Melting Point : $-23{}^{o}C$
Boiling Point : $76.8{}^{o}C$
Relative Density :$1.586$
It is insoluble in water,
It is soluble in many organic solvents, including ethanol and benzene,
It is a good solvent for waxes, lacquers, and rubbers and the main industrial use is as a solvent.
The bonding in carbon tetrachloride is covalent, as in methane.
