Question

Which is the correct Lewis structure for carbon tetrabromide (CBr4), in which a central carbon atom is bound to four atoms of the group 7A element bromine?

Answer 1

when we make a rough chemical structure its like -
br
I
br-c-br
I
br
so as we can see that its having 4 bond pairs of c-br respectively so it qualifies for the hybridisation of sp3(4 bp+ 0 lp)
thus it gives us a tetrahedral geometrical structure
