Compound 'X' of molecular formula C_(4)H_(10)O on treatment wit Lucas reagent at room temperature gives compound 'Y'. When compound 'Y' is heated with alcoholic KOH, it gives isobutene. Compound 'X' and 'Y' are respectively.

Compound 'X' of molecular formula C_(4)H_(10)O on treatment wit Lucas

1.	Compound 'X' of molecular formula C_(4)H_(10)O on treatment wit Lucas reagent at room temperature gives compound 'Y'. When compound 'Y' is heated with alcoholic KOH, it gives isobutene. Compound 'X' and 'Y' are respectively.
Answer» 2-Methyl-2-propanol and 2-Methyl-2-chloropropane 2-Methyl-1-propanol and 1-Chloro-2-methylpropane 2-Methyl-1-propanol and 2-Methyl-2-chloropropane Butane-2-ol and 2-Chlorobutane Solution :`(A) H_(3)C-UNDERSET(CH_(3))underset(\|)overset(CH_(3))overset(\|)(C)-OH underset(ZnCl_(2))overset(HCl)rarr H_(3)C-underset(CH_(3))underset(\|)overset(CH_(3))overset(\|)(C)-Cl overset("alk. KOH")rarr H_(3)C-underset(CH_(2))underset(\|\|)overset(CH_(3))overset(\|)(C)` Thus (X) is 2-methylpropan-2-ol and (Y) is 2-chloro-2-methylpropane.
