Select the correct statementabout the following reaction CH_3-undersetunderset(CH_3)(|)CH-CH_2-CH=CH_2overset(H_2//Ni)to(Y)overset(Cl_2//hv)toMonochloro products (X)

Answer»

The reactant (X) has four positional ISOMERS ( includeing 'X' itself)
The hydrogenated product Y has three positional isomers
Four monochloro products are formed which are all positional isomers
Two alkyne can GIVEN Y on hydrogenation

Solution :`CH_3-undersetunderset(CH_3)(|)CH-CH_2-CH=CH_2overset(H_2//Ni)toCH_3-undersetunderset(CH_3)(|)CH-CH_2-CH_2-CH_2`
Positional Isomers of X : (4) `CH_3-undersetunderset(CH_3)(|)CH-CH_2-CH=CH_2,CH_3-undersetunderset(CH_3)(|)CH-CH=CH=CH_3`
`CH_3-undersetunderset(CH_3)(|)C=CH-CH_2-CH_3,CH_2-undersetunderset(CH_3)(|)C-CH_2-CH_2-CH_3`
Positional isomers of Y : (2)
`CH_3-undersetunderset(CH_3)(|)CH-CH_2-CH_2-CH_3,CH_3-CH_2-undersetunderset(CH_3)(|)CH-CH_2-CH_3`
Monochloro products : (5)
`CH_3-undersetunderset(CH_3)(|)CH-CH_2-CH_2-oversetoverset(Cl)(|)CH_2,CH_3-undersetunderset(CH_3)(|)CH-CH_2-oversetoverset(Cl)(|)CH-CH_3`
`CH_3-undersetunderset(CH_3)(|)CH-oversetoverset(Cl)(|)(CH)-CH_2-CH_3,CH_3-undersetunderset(CH_3)(|)oversetoverset(Cl)(|)C-CH_2-CH_2-CH_3,oversetoverset(Cl)(|)CH_2-undersetunderset(CH_3)(|)CH-CH_2-CH_2-CH_3`
Alkyne : (2) `CH_3-undersetunderset(CH_3)(|)CH-CH_2-C=CH,CH_3-undersetunderset(CH_3)(|)CH-C-=C-CH_3`
