Question

Dimethyldichlorosilane, $\left(\left(CH\right)_{3}\right)_{2}\left(SiCl\right)_{2}$ on hydrolysis and then polymerisation produces:

• A. $\left(\left(CH\right)_{3}\right)_{2}Si\left(\right.OH\left(\left.\right)_{2}$
• B. $\left(\left(CH\right)_{3}\right)_{2}Si=O$
• C. $-\left(\left[O - \left(\right. \left(CH\right)_{3} \left(\left.\right)_{2} Si - O\right]\right)_{n}-$
• D. $\left(Me\right)_{2}SiCl\left(\right.OH\left.\right)$

Answer 1

Answer: (C)

$\left(\left(CH\right)_{3}\right)_{2}\left(SiCl\right)_{2} \rightarrow \left(\left(CH\right)_{3}\right)_{2}Si\left(\right.OH\left(\left.\right)_{2}$
The product cannot lose $H_{2}O$ molecule to form $\left(\left(CH\right)_{3}\right)_{2}Si=O$ and hence undergoes polymerization.
