(b) Oxalic acid
(c) Succinic acid
(d) Maleic acid​

Answer 1

Answer:

Hey...please mark me brainlist when u found correct answer

...option b is correct ....Oxalic acid.

Answer 2

Answer:

The correct answer is Oxalic acid.

Explanation:

Unsaturated carboxylic acids of the type  RCH=CH(CH2)nCOOH  usually exhibit the properties characteristic of isolated double bonds and isolated carboxyl groups when  n  is large and the functional groups are far apart.

With optimised reaction conditions in hand, we set out to investigate the substrate scope of the copper-catalysed conjugate reduction of α,β-unsaturated carboxylic acid derivatives . We found that the catalytic hydrogenation could be applied to a variety of aryl or alkyl substituted enoates
