An unknown substance has a boiling point of 174°C. Which statement is true about this unknown substance?
a) It has a higher boiling point than water, and it likely has stronger electrostatic forces between its molecules than water.
b) It has a higher boiling point than water, and it likely has weaker electrostatic forces between its molecules than water.
c) It has a lower boiling point than water, and it likely has weaker electrostatic forces between its molecules than water.
D) It has a lower boiling point than water, and it likely has stronger electrostatic forces between its molecules than water.

The unknown substance has a higher boiling point than water, and it likely has stronger electrostatic forces between its molecules than water.

What is the meaning of Boiling Point ?

The temperature at which a liquid's saturated vapour pressure equals the air pressure surrounding it is known as the boiling point.

It is given that an unknown substance has a boiling point of 174°C.

The boiling point of water is 100°C.

So the boiling point of the unknown substance is higher than that of water.

Higher boiling point signifies more heat required to break the bonds.

Higher boiling point means existence of strong non covalent bonds.

This means it likely has stronger electrostatic forces between its molecules than water.

Therefore Option A is the correct answer.
