1.	Startingfrom SiCl_(4), preparethe followingin steps not exceeding the number givein parentheses (giveonly reactions) : (a) Si(I) , (b) Linear siliconcontainingmethyl group(4) (c ) Na_(2)SiO_(2) (3).
Answer» Solution :(a) `SiCl_(4) + 2Mg overset(DELTA)rarr Si +2MgCl_(2)` or `3SiCl_(4) + 4Al overset(Delta)rarr 4AlCl_(3) + 3Si` (b) (i) `SiCl_(4) + Mg rarr Si +2MgCl_(2)`, (ii) `Si + 2CH_(3)Cl overset(" Cu POWDER ")underset(570 K)rarr (CH_(3))_(2)SiCl_(2)` (iii) `(CH_(3))_(2)SiCl_(2) + 2H_(2)O rarr HO-underset(CH_(3))underset(\|)overset(CH_(3))overset(\|)(Si)-OH` (IV) (c ) (i) `SlCl_(4) + 4H_(2)Orarr Si(OH)_(4) + 4HCl` (ii) `Si(OH)_(4)overset(Delta)rarr SiO_(2) + 2H_(2)O` , (iii) `SiO_(2) + 2 NaOH overset(Delta)rarr Na_(2)SiO_(3) + H_(2)O`
