An organic acid (A), `C_(5)H_(10)O_(2)` reacts with `Br_(2)` in the presence of phosphorous to give (B). Compound (B) contains an asymmetric carbon atom and yield (C) on dehydrabromination. Compound (C) does not show geometric isomerism and on decarboxylation give an alkene (D) which on ozonolysis gives (E) and (F), compound (E) gives a positive schiff's test but (F) does not. Give structures of (A) to (F) with reasons.

Text Solution

Verified by Experts

(E) is aldehyde and (F) is ketone . The number of C-atom in (A). (B) and (C) are 5and in (D) just four. It.s also clear that (A) has attlesat one `alpha` - hydrogen as it is showing HVZ reaction . Two options are possible for (A).
