Question

think about intermolecular forces and the stronger the intermolecular force the more energy needed to separate the molecules. just thinking about this, put the properties below in the correct category.

Strong intermolecular forces/ weak intermolecular force

A) high vapor pressure

B) high boiling point

C) high viscosity

d) high surface tension

Answer 1

A )

High viscosity containing substances generally posses high boiling points, they are called as non volatile substances.

They posses strong intermolecular forces so that high boiling points.

B )

High vapour pressure means weak intermolecular forces , they posses low boiling points, called as volatile substances.

C )

High boiling points means they have strong intermolecular forces, they are called as less volatile solvents.

D )

High surface tension means high intermolecular forces and high boiling points and they are called as less volatile substances.
