(ii) `CH_(3)-underset(CH_(3))underset(|)(C)H-CH=CH_(2)underset(HOH)overset(D^(+))(rarr) ?`
(iii) `C_(3)H_(6)(CH_(3)-CH=CH_(2))underset(HOH)overset(D^(+))(rarr)?`
(iv) `C_(3)H_(6)(CH_(3)-CH=CH_(2))underset(D_(2)O)overset(D^(+))(rarr)?`
(v) `C_(3)H_(6)(CH_(3)-CH=C_(2))underset(D_(2)O)overset(H^(+))(rarr)`

Explanation

[Hint]
(i)
(ii) `CH_(3)-underset(CH_(3))underset(|)(C)H-overset(OH)overset(|)(C)H-CH_(2)D`
