An organic compound having the molecular formula `C_(3)H_(6)O` can exist in the form of two isomers A and B having different functional groups. The isomer A is a liquified which is used as a solvent form nail polish. The isomer B is also liquified. An aqueous solution of one of the lower homologues of B is used for preserving biological specimens in the laboratory
(a) What is compound A?
(b) Write the electron dot structure of A.
(c) What is compound B?
(d) Write the electron dot structure of B.
(e) Name the lower homologue of compound B which is used in preserving biological specimens.
