In order to distinguish the R and S forms of a chiral molecule with a single stereocenter, an enzyme must have binding sites for how many of the groups on the stereocenter of the molecule? a. 1
b. 2
c. 3
d. 4

b) mutualism

hope this : )

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: )
