Answer: Given compounds are arranged in decreasing order of their vapor pressure as follows.

Explanation:
Vapor pressure is defined as the pressure exerted by the vapors which are present on the surface of a liquid. Less is the intermoecular forces present within the molecules of a substance more will be its vapor pressure.
For example, is a gas and there exists Vander waal forces between its molecules. Hence, it has more vapor pressure than and .
In , there exists hydrogen bonding which is stronger than bonding present in . So, has low vapor pressure.
In , there exists dipole-dipole interaction which is stronger than Vander waal forces but weaker than hydrogen bonding.
Therefore, given compounds are arranged in decreasing order of their vapor pressure as follows.
The energy is transformed into kinetic energy which makes the substance to move. The law of conservation of energy which is the first law of thermodynamics states that in a closed system energy can neither be created nor destroyed but can change from one form to another
ability of an atom to attract an electron from another atom toward itself.
Explanation:
Electronegativity is the chemical property that describes the ability of an atom to attract electron to itself. It is responsible for bond formation between atoms.
