Question

Discuss the shape of the following molecules using VSEPR model
a) BrF5 b) 8F3

Answer 1

Answer:

BrF5. distorted octahedral or square pyramidal.

Explanation:

the Br has 7 valence electrons out of which five electrons pair up with fluorine the two remaining electrons form lone pairs which offer repulsion to the bond pairs.so in order to minimise the repulsive force the shapo of BrF5 molecule is distorted octahedral or square pyramidal..

remember lonepairs-lonepair repulsion>lonepair-bondpair repulsion>bondpair bond pair repulsion.

i hope this is helpful.
