Question

The overlap of orbitals involved in the formation of C–Br bond in vinyl bromide is

• A. sp\(^3\) – 3p\(_z\)
• B. sp\(^2\) – 4p\(_z\)
• C. sp\(^3\) – 4p\(_z\)
• D. sp\(^2\) – 3p\(_z\)

Hint:

Halogens use their outermost p-orbitals while carbon uses hybrid orbitals for bond formation.

Answer 1

The Correct Option is B

Step 1: Identify hybridization of carbon in vinyl bromide.
Vinyl bromide is CH\(_2\)=CH–Br.
Carbon attached to bromine is sp\(^2\) hybridized.
Step 2: Identify orbital of bromine.
Bromine forms bond using its 4p orbital.
Step 3: Determine type of overlap.
Sigma bond is formed by overlap of sp\(^2\) orbital of carbon and 4p orbital of bromine.
Step 4: Conclusion.
Correct overlap is sp\(^2\) – 4p\(_z\).
