(a)
Interpretation:
Lewis structure for
Concept Introduction:
Lewis dot structure or electron representation is the diagram which shows the bonding between the atom in a molecule by sharing of electrons. Remaining electrons are shown as lone pair on the atom in the molecule.
Sharing of 2 electrons between two atoms results in formation of single bond, sharing of 4 electrons between two atoms results in formation of double bond and sharing of 6 electrons between two atoms results in formation of triple bond.
(b)
Interpretation:
Lewis structure of to be identified.
