Properties of covalent compounds — task. Chemistry CBSE Live product, Class 10 (2026-27).

Answer the following questions:

Aryan records the following observations during different reactions:

Property	X	Y	Z
Melting point	Low	High	High
Solubility in water	Insoluble	Soluble	Insoluble
Conductivity	No	Yes	No

1. Aryan asked why do many covalent compounds dissolve in organic solvents like benzene or petrol?

Covalent compounds are non-polar and organic solvents are generally polar
Covalent compounds are polar and organic solvents are generally non-polar
Both covalent compounds and organic solvents are generally non-polar
Both covalent compounds and organic solvents are generally polar

2. Which combination of properties is characteristic of most covalent compounds?

Low melting point, insoluble in water, poor conductor of electricity
High melting point, soluble in water, conduct electricity
Low melting point, conduct electricity in aqueous solution
High melting point, insoluble in benzene, conduct when molten

3. Aryan says, "All covalent compounds have low melting points." Is the statement correct? Justify your answer. Justify your answer.
