$2-$Bromo$-4,5-$dimethylhept$-3-$ene

(A) $1$. Identify the longest carbon chain containing the double bond. The longest chain has $7$ carbon atoms,so the parent alkane is heptane,and with the double bond,it is hept$-3-$ene.$2$. Number the chain from the end that gives the lowest locant to the double bond. Numbering from the right gives the double bond position $3$.$3$. Identify the substituents: there is a bromo group at position $2$ and methyl groups at positions $4$ and $5$.$4$. Combining these,the $IUPAC$ name is $2-$Bromo$-4,5-$dimethylhept$-3-$ene.
