`Si(CH_(3))_(2)Cl_(2)` is hydrolysed. What type of polymer is formed ? 

Explanation

Hydrolysis of `Si(CH_(3)) _(2)Cl_(2)` is given as
`Si(CH_(3))_(2)Cl_(2)overset(H_(2)O,OH^(-))rarrSi(CH_(3))_(2)(OH)_(2)`
The hydrolysis product undergoes condensation homopolymerisation. The product is an example of inorganic polymer, called polysiloxane.
