Vedclass · Answer

(C) The given structure is $CH_3-CH(CH_2-CH_3)-CH_2-Br$.Expanding the ethyl group,we get $CH_3-CH_2-CH(CH_3)-CH_2-Br$.The longest carbon chain containing the bromine atom has $4$ carbon atoms,so the parent alkane is butane.Numbering the chain from the end closer to the bromine atom,we get $Br$ at $C1$ and a methyl group at $C2$.According to $IUPAC$ rules,substituents are listed in alphabetical order (bromo before methyl).Therefore,the $IUPAC$ name is $1$-bromo-$2$-methylbutane.

Which is the correct $IUPAC$ name for: $CH_3-CH(CH_2-CH_3)-CH_2-Br$?
