Read the following write-ups and answer the questions at the end of it.
Silicons are synthetic polymers containing repeated `R_(2)SiO` unit. Since, the imperical formula of a ketone `(R_(2)CO)`, the name silicone has been given to this materials. silicons can be made into oils, rubberly elastamors and resins. They find a variety of applications because of their chemical inertness,water repelling nature, heat-resistence and good electrical insulating property.
Commercial silicone polymers are usally methyl derivatives and to lesser a extent phenyl derivatives and are synthesised by the hydrolysis of
`R_(2)SiCl_(2)` [R =methyl (Me) or phenyl `(phi)`]
`Me_(2)SiCl_(2) overset(H_(2)O)to O-overset(Me)overset(|)underset(Me)underset(|)(Si)-O-overset(Me)overset(|)underset(Me)underset(|)(Si)-O-overset(Me)overset(|)underset(Me)underset(|)(Si)-O-`
If we start with `MeSiCl_(3)` as the starting material, silicons formed is :
A. `Me-overset(Me)overset(|)underset(Me)underset(|)(Si)-O-overset(Me)overset(|)underset(Me)underset(|)(Si)-O-overset(Me)overset(|)underset(Me)underset(|)(Si)-O-overset(Me)overset(|)underset(Me)underset(|)(Si)-Me`
