Question

Which statement is true about liquids?

A. They flow and are not compressable.

B. They flow and are compressable.

C. They flow and are highly ordered.

D. They are ordered and compressable.

E. They do not assume the shape of their containers.

Which compound has the highest boiling point?

	A. CH3CH2CH3
	B. CH3CH3
	C. C(CH3)4
	D. CH4
	E. CH3CH2CH2CH2CH3

Answer 1

1)

Liquids and gas can flow

Liquids are un compressible but gas are compressible

Liquid assume the shape of container

Answer: A

2)

All of these compounds will have Dispersion force as their intermolecular force of attraction

Dispersion force is directly proportional to molar mass

Molar mass is maximum for C and E

But boiling point of E will be higher since its shape is linear unlike C whose shape is spherical

Spherical shape means less area of contact between different molecules and hence less dispersion forces

Answer: E
