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.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
