Which of these choices best describes the interpretation of the following peak that may be recorded in a 1H NMR spectrum? a. Ar-CHCO2H
b. Ar-CHCHX2
c. Ar-CHCH2X
d. Ar-CHCH3
e. None of these interpretations describes this peak.

b. Ar-CHCHX2

Explanation:

The hydrogen atoms when combine with carbon atoms forms the carbon hydrogen molecule. There is 1H NMR which means two hydrogen atoms are adjacent to the carbon atoms. The correct choice is b and there is one hydrogen and one carbon atoms adjacent to each other forming a molecule.

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.
