The Lewis structure of
Concept Introduction:
A covalent bond is a bond that is formed from the mutual sharing of electrons between atoms. Lewis structures are representations of the covalent bond. In this, Lewis symbols show how the valence electrons are present in the molecule.
Steps to write Lewis structures are as follows:
1. The skeleton structure with single bonds between all bonded atoms has to be written
2. Sum the valence electrons of the atoms in the molecule.
(a) For cations, one electron is subtracted for each positive charge.
(b) For anions, one electron is added for each negative charge.
3. Subtract two electrons from total number of valence electrons for each bond in the skeleton structure.
4. Count the number of electrons required to satisfy the octet rule for each atom in the structure. If the number of electrons needed is less than the number remaining, add one bond for every two electrons needed between atoms to attain an octet.
5. The remaining electrons are placed as lone pairs on atoms that need them to satisfy the octet rule.
In octet rule, the central has eight electrons around it. The molecules that have more than eight electrons around it does not obey the octet rule.

The stationary phase is always more polar The mobile phase is always more polar It depends on our choices for both stationary and mobile phase Their polarity doesn't really matter so we never consider itarrow_forward
