Answer»

SOLUTION :EIGHT isomers having molecular formula are LISTED below. Their IUPAC names are given against them.
`1^(@) ` for primary
`2^(@) ` for secondary
`3^(@) ` for tertiary
`CH_(3)CH_(2)CH_(2)CH_(2)CH_(2)Br"1-Bromopentane " (1^(@))`
`CH_(3)CH_(2)CH_(2)CH(Br) CH_(3) "2-Bromopentane " (2^(@))`
`CH_(3)CH_(2)CH(Br)CH_(2)CH_(3) "3-Bromopentane " (2^(@))`
`(CH_(3))_(2)CHCH_(2)CH_(2)Br "1-Bromo -3-methylbutane " (1^(@))`
`(CH_(3))_(2)CHCHBrCH_(3) "2-Bromo-3-methylbutane " (2^(@))`
`(CH_(3))_(2)CBrCH_(2)CH_(3) "2-Bromo -2-methylbutane " (3^(@))`
`CH_(3)CH_(2)CH(CH_(3))CH_(2)Br "1-Bromo -2- methylbutane " (1^(@))`
