Concept explainers
(a)
Interpretation:
An orbital overlap picture of ethane with carbon atoms
Concept introduction:
By using the VSEPR theory, the structural geometry of an atom can be determined.
Molecular geometry is defined as the 3-dimensional shape of molecule occupies in space.
The total number of electrons needs to be calculated first which is equal to the sum of number of bonding pair of electrons and lone pair of electrons.
(b)

(c)
Interpretation:
The reason for structure in part (a) to be more stable than structure in part (b) needs to be explained.
