Vedclass · Answer

(B) $1$. Identify the longest carbon chain. The longest chain contains $6$ carbon atoms,so the parent alkane is hexane. $2$. Number the chain from the end that gives the substituents the lowest possible locants. $3$. The structure is $CH_3-CH(CH(CH_3)_2)-CH_2-CH_2-CH_3$. Expanding the isopropyl group: $CH_3-CH(CH_3)-CH(CH_3)-CH_2-CH_2-CH_3$. $4$. Numbering from left to right gives methyl groups at positions $2$ and $3$. $5$. Therefore,the $IUPAC$ name is $2,3-$dimethylhexane.

Column $I$ (Structure)	Column $II$ ($IUPAC$ Name)
$(A)$ $CH_3-CH=CH-CH_2Br$	$(p)$ $1$-Bromobut-$2$-ene
$(B)$ $CH_2=C(CH_3)-CH_2Br$	$(q)$ $3$-Bromo-$2$-methylpropene
$(C)$ $CH_3-C(CH_3)=CH-CH_2Br$	$(r)$ $4$-Bromopent-$2$-ene
$(D)$ $CH_3-CH=CH-CH_2CH_2Br$	$(s)$ $1$-Bromo-$2$-methylbut-$2$-ene

The $IUPAC$ name of the following compound is $CH_3-CH(CH(CH_3)_2)-CH_2-CH_2-CH_3$.
