`Phenol overset(Zn)underset(Dust) rarrXoverset(C_(2)H_(5)Cl)underset(Anhydrous AlCl_(3))(rarr)Y`; number of structural isomers of Y are

Consider the following reaction Phenol overset(Zn)underset("dust")rarr X overset(CH_(3)CI)underset(underset(AICI_(3))("Anhydrous"))rarr Y overset("Alkaline")underset(KMnO_(4))rarrZ The product Z is

C_(6)H_(6)overset(HNO_(3))underset(H_(2)SO_(4))rarr X overset(Cl_(2))underset(FeCl_(3))rarr Y In the above sequence Y can be

C_(2)H_(6)overset((CH_(3)COO)_(2)Mn)rarr X overset(PCl_(5))rarr Y overset(C_(6)H_(6))underset("Anhy." AlCl_(3))rarr Z . Identify X, Y and Z :

"Propionic acid"overset(PCl_(5))toXoverset(C_(6)H_(6))underset(AlCl_(3))toY . In the above sequence Y is

In the sequence of reactions C_(6)H_(5)Broverset(Mg)underset("ether")rarr (X) overset((i)CO_(2))underset((iii)H_(3)O^(+))rarr(Y) the product (Y) is

Assertion (A): Following are the structural isomers of boutane. H-underset(H)underset(|)overset(H)overset(|)(C)-underset(H)underset(|)overset(H)overset(|)(C)-underset(H)underset(|)overset(H)overset(|)(C)-underset(H)underset(|)overset(H)overset(|)(C)-H H-underset(H)underset(|)overset(H)overset(|)(C)-underset(H-underset(H)underset(|)(C)-H)underset(|)overset(H)overset(|)(C)-underset(H)underset(|)overset(H)overset(|)(C)-H Reason (R): Structural isomers have the same molecular formula but they differ in their structures.
