Question

When two halogen atoms are attached to same carbon atom then it is called as:

• A. $\text{gem-dihalide}$
• B. $\text{vic-dihalide}$
• C. $\alpha ,\omega -\text{halide}$
• D. $\alpha ,\beta -\text{halide}$

Answer 1

Answer: (A)

$\text{gem-dihalide}$
The dihaloalkanes having identical halogen atoms are termed as alkylidene or alkylene dihalides. They can be divided into two types: Geminal dihalides- When the halogen atoms are placed on the same carbon atom. Vicinal dihalides- When the halogen atom are placed on the adjacent carbon atoms. Hence, the correct answer is option (a).
