Write structures and IUPAC names of different structural isomers of alkenes corresponding to ` C_(5)H_(10)`.

Explanation

(a) `CH_(2) = CH - underset("Pent-1-ene" ) (CH_(2) - CH _(2) - CH _(3))`
(b) `CH_(3) - CH = underset( "Pent-2-ene") (CH- CH _(2)- CH _(3))`
(c) `{:(CH _(3) - underset( CH _(3)) underset( |) (C) = CH - CH _(3)), (" ""2-Methylbut-2-ene"):}`
(d) `{:(CH _(3) - underset( CH _(3)) underset( |) (C) = CH - CH _(3)), (" ""3-Methylbut-1-ene"):}`
(e) `{:(CH _(2) - underset( CH _(3)) underset( |) (C) = CH - CH _(3)), (" ""2-Methylbut-1-ene"):}`
