Question
How are silicones prepared? Write its two uses.
✓
Answer
Preparation of Silicones:
Methyl chloride (or any other alkyl or aryl chloride) reacts with silicon in presence of copper catalyst at 573K, methyl substituted chlorosilanes are produced. Hydrolysis of dialkyl chlorosilanes, followed by condensation polymerisation yields silicones.
