How many cyclic and acyclic isomers are possible for the molecular formula `C_3 H_6 O` ? Draw these.

Explanation

Seven isomers are possible. These are :
(a) Acyclic isomers:
(i) `CH_3 CH_2 CHO` Propanal
(ii) `CH_3 overset(overset(O)||)C CH_3` Propanone
(iii) `CH_3 = CH CH_2 OH` Prop - 2 - en - 1 - ol
(iv) `CH_2 = CHO CH_2` Methoxyethene
(b) Cyclic isomers :
(v)
