Answer:
The two constitutionally isomeric compounds that result from the reaction between sodium nitrite (NaNO2) and 2−Iodooctane are the following:
We shall consider V, the volume and T, the temperature.
According to Boyle's Laws:

In our case:
Answer:
C) a low heat of vaporization.
Explanation:
It is C) a low heat of vaporization.
Low heat of vaporization means less amount of energy is required to vaporize a liquid. This further means the liquid has weaker intermolecular force of attraction that is why on provide lesser heat only it vaporizes.
Low vapor pressure, high boiling point and high critical temp. all contribute to strong intermolecular forces in a liquid
