Compound 'A' (C_(10)H_(12)O) evolves H_(2) gas with Na metal. It reacts with Br_(2) // C CI_(4) to give B( C_(10)H_(12)Br_(2)O) with I_(2)//NaOH it forms iodoform and acid C[C_(9)H_(8)O_(2)]. A has geometrical and optical isomers. The structure of A and C should be.

Answer»


Ph. CH=CHCOOH

Solution :COMPOUND A (`C_(10)H_(12)O`) -OH GROUPS reacts with Na to liberate `H_(2)`
C = C and `C -= C` groups decolourise `Br_(2) // C Cl_(4)`, `A=C_(6)H_(5)-CH=CH-overset(OH)overset(|)CH-CH_(3)` Compound `C(C_(9)H_(8)O_(2))`, `A overset(I_(2)+NaOH)to Ph-CH=CH-COOH+CHI_(3)`
