- BAmmonical $C{u_2}C{l_2}$
- CAmmonical $AgN{O_3}$
- ✓Solution of $B{r_2}$ in $CC{l_4}$
✓
Answer
Correct option: D.
Solution of $B{r_2}$ in $CC{l_4}$
d
(d)Solution of bromine in carbon tetrachloride is used to test for unsaturation of alkene. Red colour of bromine disappears due to the formation of colourless dibromo ethane $({C_2}{H_4}B{r_2})$.
