The acid D obtained through the following sequence of reactions is:
`C_(2)H_(5)Br overset(Alc. KOH)rarrA overset(Br_(2))underset(C Cl_(4))rarrBoverset(KCN)underset((excees))rarrCoverset(H_(3)O^(+))rarr`

A

succinic acid

B

malonic acid

C

maleic acid

D

Oxalic acid.

Text Solution

Verified by Experts

The correct Answer is:
A
`C_(2)H_(5)Br overset("Alc. KOH")to CH_(2)=CH_(2)overset(Br_(2)//C Cl_(4))to CH_(2)Br-CH_(2)Br overset(KCN)to N C CH_(2)-CH_(2)CN overset(H_(3)O^(+))to underset("Succinic acid")(HOO C CH_(2)-CH_(2)COOH)`.
