A pleasant smelling optically active ester (A) has M.W. = 186. It does not react with `Br_(2)` in `"CC"l_(4)` . Hydrolysis of (A) gives two optically active compounds (B) soluble in NaOH and (C). Compound (C) gives a positive iodoform test and on warming with conc. `H_(2)SO_(4)` gives (D) (Saytzeff-product) with no geometrical isomers. (C) on treatment with benzene sulphonyl chloride gives (E) which on treatment with NaBr gives optically active (F). When `Ag^(+)` salt of (B) is treated with `Br^(2)` ,racemic (F) is formed. Give the structures of (A) to (F).
