Question

1.-Which of these choices best describes the interpretation of the following peak that may be recorded in a ¹H NMR spectrum? 0.9? (3H, s). The quoted hydrogen atom is intended to be the one producing the peak that we are interpreting.

                A) O=C-C(C)2C’H’3

                B) O=C-CHC’H’3

                C) O=C-CH2C’H’3

                D) None of these interpretations describes this peak.

2.- Which of these choices best describes the interpretation of the following peak that may be recorded in a ¹H NMR spectrum? 4.3? (1H, q). The quoted hydrogen atom is intended to be the one producing the peak that we are interpreting.

                A) O-C’H’CO2H

                B) O-C’H’CHX2

                C) O-C’H’CH2X

                D) O-C’H’CH3

                E) None of these interpretations describes this peak.
