- ✓$(CH_3)_2SiCl_2$
- B$(SiH_3)_3N$
- C$SiCl_4$
- DAll
✓
Answer
Correct option: A.
$(CH_3)_2SiCl_2$
a
Silicones are a group of organosilicon polymers, which have $\left(-\mathrm{R}_{2} \mathrm{SiO}-\right)$ as a repeating unit.
Silicones are a group of organosilicon polymers, which have $\left(-\mathrm{R}_{2} \mathrm{SiO}-\right)$ as a repeating unit.
The starting materials for the manufacture of silicones are alkyl or aryl substituted silicon chlorides, $\mathrm{R}_{\mathrm{n}} \mathrm{SiCl}_{(4-\mathrm{n})}$, where $\mathrm{R}$ is alkyl or aryl group.
On hydrolysis of this alkyl or aryl substituted silicon chlorides the silicones are formed.
Among given options, option A is the only alkyl substituted silicone chloride and hence it is correct answer.
