Answer 1

1. What atomic or hybrid orbitals make up the sigma bond between Br and Cl in bromine trichloride, BrCl₃?​

hybridization around Br = sp³d

and chlorine electronic configuration is :-[Ne] 3s2 3p5

_sp3d____orbital on Br

+

_3p_____orbital on Cl

molecular geometry = T shaped

What are the approximate Cl-Br-Cl bond angles? 90^o and 180^o(less than 90^o and less than 180^o)

2. What atomic or hybrid orbitals make up the sigma bond between C₂ and C₃ in propylene,CH₂CHCH₃?
(C₂ is the second carbon in the structure as written.)

__sp2___orbital on C2

+

__sp3_____orbital on C3

What is the approximate C₁-C₂-C₃ bond angle? 120^o
