Write structures of compounds A, B and C in each of the following reactions : (i) C_(6)H_(5)Br overset("Mg/dry ether")to A underset((b)H_(3)O)overset((b)CO_(2)(g))to B overset(PCl_(5)) to C (ii) CH_(3)CN overset((a)SnCl_(2)//HCl)underset((b)H_(3)O^(+)) to A overset("dil NaOH") to B overset(Delta) to C

Answer»

Solution :(i) `A = C_(6)H_(5)MgBr` (Phenyl magnesium bromide)
B= `C_(6)H_(5)COOH` (Benzoic ACID)
`C = C_(6)H_(5)COCL` (BENZOYL chloride)
(ii) `A = CH_(3)CHO`
`B = CH_(3) - UNDERSET(OH)underset(|)CH-CH_(2)-CHO` (Aldol)
`C =CH_(3)-CH - CHO` (But-2-enal)
