The IUPAC name of the above compound is 2-chloro-3-methylbutane.
Here 2-chloro is for the chloride group (−Cl) attached at position C−2 while 3-methyl is for the methyl group (−CH
3
) attached at the position C−3 and butane is for the long chain of 4 carbon atoms.
Hence the IUPAC name of the above compound is 2-chloro-3-methylbutane.

The IUPAC name of the above compound is 2-bromo-3-methylbutane.
Here 2-bromo is for the bromide group (−Br) attached at position C−2 while 3-methyl is for the methyl group (−CH
3
) attached at the position C−3 and butane is for the long chain of 4 carbons.
Hence the IUPAC name of the above compound is 2-bromo-3-methylbutane.

The IUPAC name of the above compound is 4-bromo-4-methylpent-2-ene.
Here 4-bromo is for the bromide group (−Br) attached at position C−4 while 4-methyl is for the methyl group (−CH
3
) attached at the position C−4 and pent-2-ene is for the long chain of 5 carbon atoms havinf double bond at position C−2.
Hence the IUPAC name of the above compound is 4-bromo-4-methylpent-2-ene.
