Answer»

`CH_(3)-CH_(2)-CH_(2)-CH_(3)` and `CH_(3)-underset(CH_(3))underset(|)(CH)-CH_(3)`
`CH_(3)-CH_(2)-CH = CH_(2)` and `CH_(3)-CH=CH-CH_(3)`
`CH_(3)-CH_(2)OH` and `CH_(3)-O-CH_(3)`
`{:(""CH_(3)),("|"),(CH_(3)-C-CH_(3)),("|"),(""CH_(3)):}` and `CH_(3)-CH_(2)-CH_(2)-CH_(2)-CH_(3)`

SOLUTION :`underset("1-butene")(CH_(3)-CH_(2)-CH)=CH_(2)` & `underset("2-butene")(CH_(3)-CH_(2)=CH-CH_(3))`
