Answer:
According to VSEPR theory the molecule with six binding domains and single lone pair will have the pentagonal bipyramidal geometry. As it is known that six binding domains means six bonds and a single lone pair means one pyramidal bond, so that it does not repel bonds to a higher extent. Hence, total of seven bonds are required which is provided by the pentagonal bipyramidal geometry. The number of electrons of the molecule will be fourteen 2 from each of the 6 binding domains that makes up to 12 and 2 from the lone pair.
