An acidic compound $$(A)$$. $$({C}_{4}{H}_{8}O)$$ loses its optical activity on strong heating yielding $$(B)$$ $$({C}_{4}{H}_{6}{O}_{2})$$ which reacts readily with $$KMn{O}_{4}$$. $$(B)$$ forms a derivative $$(C)$$ with $$SO{Cl}_{2}$$ which on reaction with $${({CH}_{3})}_{2}NH$$ gives $$(D)$$. The compound $$(A)$$ on oxidation with dilute chromic acid gives an unstable compound $$(E)$$ which decaboxylates 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.
