One end of the molecule tends to be partially positively charged and the other end tends to be partially negatively charged. This type of chemical bonding is called a hydrogen bond and is responsible for many of the properties exhibited by water. Therefore, we have a double bond between one N and one of the two O atoms. Firstly read the entire NCERT chapter. These chemical bonds are what keep the atoms together in the resulting compound.

Chemical Bonding of Class 9 Most of the substances found in nature are in the form of clusters or aggregates of atoms. LACO (linear combination of atomic orbitals) also discuss. Generally, the valency of an element is either equal to the number of dots in the corresponding Lewis symbol or 8 minus the number of dots (or valence electrons). JEE Main Chemistry notes comprise of three different parts which are Physical Chemistry, Organic Chemistry, and Inorganic Chemistry. Any such aggregation in which atoms are held together and which is electrically neutral is called a molecule. They can do so by losing, gaining or sharing of electrons. In (A) the oxygen-oxygen bond on the left is a double bond and the oxygen-oxygen bond on the right is a single bond. Hence the hybridized orbitals also are in the same plane giving rise to square planar geometry. For example, MgCl2, the magnesium ion, and chlorine ions are held together by force of electrostatic attraction.

During chemical bonding, when the atoms come closer to each other, the attraction takes place between them and the potential energy of the system keeps on decreasing till a particular distance at which the potential energy is minimum. Step 3: Drawing a single bond between C and O and completing octet on O, the remaining two electrons are lone pair on C. Step 4: This does not complete the octet of carbon, and hence we have a triple bond. Chemical Bonding | MOT | CBSE 11 | Notes.
