Vedclass · Answer

(C) Birch reduction of aromatic rings follows specific rules based on substituents:$(i)$ Toluene with $Na/liq. NH_3$ gives $1-$methyl$-1,4-$cyclohexadiene. This is correct.(ii) Benzene with $Na/liq. NH_3$ gives $1,4-$cyclohexadiene. This is correct.(iii) Toluene with $Na/liq. NH_3$ gives $1-$methyl$-1,4-$cyclohexadiene. The structure shown is incorrect.(iv) Benzoic acid with $Na/liq. NH_3$ gives $1-$carboxy$-2,5-$cyclohexadiene. The structure shown is incorrect.$(v)$ Naphthalene with $Na/liq. NH_3$ gives $1,4,5,8-$tetrahydronaphthalene. The structure shown is incorrect.(vi) Anthracene with $Na/liq. NH_3$ gives $9,10-$dihydroanthracene. The structure shown is incorrect.(vii) $2-$butyne with $Na/liq. NH_3$ gives trans$-2-$butene,not cis$-2-$butene. This is incorrect.Thus,the reactions that do not represent the major product are $iii, iv, v, vi, vii$. Among the given options,option $C$ $(iv, v, vi)$ contains the most incorrect representations.

Which of the following reactions do not represent the major product of given Birch reductions?
