ALDEHYDES AND KETONES
What are aldehydes and ketones?
Aldehydes and ketones as carbonyl compounds
Aldehydes and ketones compounds which contain a carbonyl group ,i.e., a carbon-oxygen double bond. In aldehydes, the carbonyl […]

LEWIS DOT STRUCTURE
VALENCE BOND THEORY
According to this theory the valence electrons are involved in the process of bonding between the two atoms. The Basic purpose of this theory is to draw The Lewis Dot structure of the molecule in 2 dimensional space.
What is a Lewis dot structure?

CHEMICAL BOND
It is a strong force of attraction, which holds together the atoms in a molecule or crystal. A chemical bond usually has energies of the order of 1000 kj/Mol. A chemical bond may be formed, because of two reasons;
To complete the octet of the […]
PERIODICITY IN PROPERTIES
On moving along the elements of the periodic table in the order of atomic number there is a regular gradation in the properties of the elements. This is due to the similar outer electronic configuration of these elements. Some of the few gradations in the properties […]
