An acidic compound (A) C_(4)H_(8)O_(3) loses its optically activity on strong heating yielding (B), C_(4)H_(6)O_(2) which reacts readily with KMnO_(4). (B) forms a derivative (C ) with SOCl_(2), which on reaction with (CH_(3))_(2)NH gives (D). The compound (A) on oxidation with dilute chromic acid gives an unstable compound (E) hich decarboxylates readily to give (F), C_(3)H_(6)O. The compound (F) gives a hydrocarbon (G) on treatment with amalgamated Zn and HCl. Give the structures of (A) to (G) with proper reasoning.

1.	An acidic compound (A) C_(4)H_(8)O_(3) loses its optically activity on strong heating yielding (B), C_(4)H_(6)O_(2) which reacts readily with KMnO_(4). (B) forms a derivative (C ) with SOCl_(2), which on reaction with (CH_(3))_(2)NH gives (D). The compound (A) on oxidation with dilute chromic acid gives an unstable compound (E) hich decarboxylates readily to give (F), C_(3)H_(6)O. The compound (F) gives a hydrocarbon (G) on treatment with amalgamated Zn and HCl. Give the structures of (A) to (G) with proper reasoning.
Answer» Solution :Compound (A) is a HYDROXY compound and is optically ACTIVE `CH_(3)-underset(OH)underset(\|)overset(H)overset(\|)C-CH_(2)COOH` On heating it gives an UNSATURATED compound which reacts with `KMnO_(4)`
