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
