Vedclass · Answer

(C) The mono-bromination of $1-$methylcyclohex$-1-$ene via free radical substitution involves the formation of various allylic radicals.$1$. Allylic radical at the $CH_3$ group: This leads to $3-$bromomethylcyclohex$-1-$ene (achiral) and $1-$bromomethylcyclohex$-1-$ene (achiral).$2$. Allylic radical at $C_3$ position: This leads to $3-$bromo$-1-$methylcyclohex$-1-$ene,which has a chiral center,resulting in $2$ enantiomers.$3$. Allylic radical at $C_6$ position: This leads to $6-$bromo$-1-$methylcyclohex$-1-$ene,which has a chiral center,resulting in $2$ enantiomers.$4$. Allylic radical at $C_2$ position: This leads to $2-$bromo$-1-$methylcyclohex$-1-$ene,which has a chiral center,resulting in $2$ enantiomers.Considering all possible allylic positions and the resulting stereoisomers,the total number of isomers formed is $8$.

Column-$I$	Column-$II$
$(A)$ Carbocation	$(1)$ Cyclohexane and $1$-hexene
$(B)$ Nucleophile	$(2)$ Conjugation of electrons of $C-H$ $\sigma$-bond with empty $p$-orbital present at adjacent positively charged carbon
$(C)$ Hyperconjugation	$(3)$ $sp^{2}$ hybridised carbon with empty $p$-orbital
$(D)$ Isomers	$(4)$ Ethyne
$(E)$ $sp$ hybridisation	$(5)$ Species that can receive a pair of electrons
$(F)$ Electrophile	$(6)$ Species that can supply a pair of electrons

The maximum number of possible isomers (including stereoisomers) which may be formed on mono-bromination of $1-$methylcyclohex$-1-$ene using $Br_2$ and $UV$ light is. . . . . .
