The correct Answer is:
A, B, C, D
(i)`3SiCl_(4)`(vapour)+`4Al`(molten)`to4AlCl_(3)+3Si`
(ii)(a)`3SiCl_(4)+4Al to 4AlCl_(3)+3Si` , (b)`Si+2CH_(3)Cl underset(570^(@)C)overset("Cu powder")to (CH_(3))_(2)SiCl_(2)`
( c)`(CH_(3))_(2)SiClunderset(-2HCl)overset(2H_(2)O)toHO-undersetunderset(CH_(3))(|)oversetoverset(CH_(3))(|)(Si)-OH` , (d)`nHO-undersetunderset(CH_(3))(|)oversetoverset(CH_(3))(|)(Si)-OH underset(-n H_(2)O)overset(Delta)to`
(iii)(a)`SiCl_(4)+4H_(2)OtoH_(4)SiO_(4)` or `Si(OH)_(4)` (ortho silicic acid)+`4HCl`
(b)`H_(4)SiO_(4)overset(Delta)to SiO_(2)+2H_(2)O`
( c)`SiO_(2)+Na_(2)CO_(3) overset(1400^(@)C)to Na_(2)SiO_(3)+CO_(2)`

Silicones are synthetic polymers containing repeated R_2 SiO units . Since the empirical formula is that of a ketone (R_2 CO) , the name Silicone has been given to these materials . Silicone can be made into oils , rubbery elastomers and resins . They find a variety of applications because of their chemical inertness , water repelling nature, heat resistance and good electrical insulating property . Commerically silicon polymers are usually synthesised by the hudrolysis of R_2 SiCl_2 [R = Methyl (Me ) or phenyl ( phi)] . If we start with SiMeCl_3 as the starting material silicones formed is :
