MCQ
Which of the following is a gemdihalide
- A$C{H_3}.CHBr.CHBr.C{H_3}$
- B$C{H_2}Br.C{H_2}Br$
- C$CHBr = CHBr$
- ✓$C{H_3}CHB{r_2}$
✓
Answer
Correct option: D.
$C{H_3}CHB{r_2}$
d
(d) In gemdihalide both the halogen atoms are present on the same carbon atom while in vicdihalide both the halogen atoms are present on adjacent carbon atoms.
(d) In gemdihalide both the halogen atoms are present on the same carbon atom while in vicdihalide both the halogen atoms are present on adjacent carbon atoms.
$\mathop {C{H_3} - CHB{r_2}}\limits_{{\rm{Gemdihalide}}} $ $\mathop {\mathop {C{H_2}}\limits_{\mathop {|\,\,\,\,\,\,\,}\limits_{Br\,\,\,} } - \mathop {C{H_2}}\limits_{\mathop {|\,\,\,\,\,\,\,\,}\limits_{Br\,\,\,\,} } }\limits_{vic{\rm{ - }}{\rm{dihalide}}} $
