Hydrogen peroxide (H2O2) is a syrupy liquid with a relatively low vapor pressure and a normal boiling point of 152.2°C. Rationalize the differences of these physical properties from those of water.
Interpretation Introduction
Interpretation:
Rationalize why the physical properties of hydrogen peroxide – boiling point and vapor pressure, differ from that of water.
Concept introduction:
Hydrogen peroxide is a syrupy liquid. It has “open book structure” whereas water molecule has bent shape.
Boiling point and vapor pressure of a liquid is influenced the strength of intermolecular forces present between their molecules. Strong intermolecular forces results in high boiling point and low vapor pressure of the liquid.
Explanation of Solution
Explanation
The molecules of water are held together to a quite large extent through hydrogen bonding between them and due to which water remains liquid by association of its molecules. Hydrogen bonding is a kind of intermolecular force that exists in water and it is quite strong in it.
Analyze the structure of hydrogen peroxide and the nature of the intermolecular forces present in it.
The structure of hydrogen peroxide resembles that of an open book. The two oxygen atoms present in it results in hydrogen bonding between their molecules.
Structure of Hydrogen peroxide
Like water, hydrogen peroxide also exhibits hydrogen bonding...
