The products expected to be formed in the Wurtz reaction of a mixture of neopentyyl bromide and isobutyl bromide are (i) 2,2,4-trimethylpentane (ii) 2,2,5,5-tetramethylhexane (iii) 2,2,4,4-tetramethylhexane (iv) 2,5-dimethylhexane (v) 2,2,5-trimethylhexane

The products expected to be formed in the Wurtz reaction of a mixture

1.	The products expected to be formed in the Wurtz reaction of a mixture of neopentyyl bromide and isobutyl bromide are (i) 2,2,4-trimethylpentane (ii) 2,2,5,5-tetramethylhexane (iii) 2,2,4,4-tetramethylhexane (iv) 2,5-dimethylhexane (v) 2,2,5-trimethylhexane
Answer» (ii), (iii) and (v) (ii), (iv) and (v) (i), (iv) and (v) (i), (iii) and (v) Solution :`underset("NEOPENTYL bromide (A)")(CH_(3)-underset(CH_(3))underset(\|)OVERSET(CH_(3))overset(\|)(C)-CH_(2)Br)+underset("ISOBUTYL bromide (B)")(BrCH_(2)-overset(CH_(3))overset(\|)(C)H-CH_(3)) underset(("WURTZ reaction"))overset("Na/dry ether, "Delta)to underset("2,2,5,5-Tetramethylhexane (ii) (DIMERIZATION product of A)")(CH_(3)-underset(CH_(3))underset(\|)overset(CH_(3))overset(\|)(.^(@)C)-CH_(2)-CH_(2)-underset(CH_(3))underset(\|)overset(CH_(3))overset(\|)(.^(5)C)-CH_(3))+underset("2,5-Dimethylhexane (v) (Dimerization product of B)")(CH_(3)-overset(CH_(3))overset(.^(2)C)H-CH_(2)-CH_(2)-overset(CH_(3))overset(.^(5)C)H-CH_(3))` `underset("2,2,5-Trimethylhexane (iv) (Cross product of A and B)")(+CH_(3)-underset(CH_(3))underset(\|)overset(CH_(3))overset(\|)(.^(2)C)-CH_(2)-CH_(2)-overset(CH_(3))overset(\|)(.^(5)C)H-CH_(3))` thus, option (b) is correct.
