Question

What properties would you expect for CCl4? Select all that apply.

Answer 1

Answer is: It is likely a gas or liquid at room temperature.  

Carbon tetrachloride or tetrachloromethane (CCl₄) is an organic compound with nonpolar covalent chemical bonds.

1) Carbon tetrachloride is a colourless liquid, used in fire extinguishers.

2) Because it is nonpolar, it is not soluble in polar water.

3) It can not conduct electricity because it is nonpolar compound.

4) Melting point is low -23°C.

Answer 2

Answer: Option (a) is the correct answer.

Explanation:

As both carbon and chlorine are non-metals. Therefore, both of them tend to share their valence electrons in order to attain stability.

Therefore, $CCl_{4}$ is a covalent compound. This is because a compound formed by sharing of electrons by the combining atoms is known as a covalent compound.

And, covalent compounds are brittle in nature due to weak bonding between the combining atoms.

Hence, $CCl_{4}$ will most most likely be a gas or liquid at room temperature and not a solid.

It will also have low melting point and it will not be able to conduct heat and electricity as it is covalent in nature.

Thus, we can conclude that it is likely a gas or liquid at room temperature is the property that you would expect for $CCl_{4}$.
