Answer

See the explanation below.

Work Step by Step

a) Notice that meta absorbs 5C in the NMR and 4H NMR while para happens to absorb 3C in the NMR and 2H in the NMR. b) H00CCH2CH2COOH will absorb 2C in the NMR and 2H in the NMR. While CH3CH(COOH)2 absorbs 3C NMR and 3H NMR. c) In this scenario, the acid used, absorbs nearly 128 deltas while the other non-acid only absorbs 108 delta. d) Cyclic absorbs 4C in the NMR and 4H in the NMR while the linear isomer will absorb 6C in the NMR and 5H NMR.
