Answer:
Functional groups
Explanation:
A functional group refers to an atom or cluster of atoms that are covalently bonded to carbon and influence the behavior of organic compounds.
There are several functional groups in organic chemistry that determine the properties of organic compounds.
For instance, in the compound CH3CH2CH2CH2OH, the functional group is the -OH group. The chemical and physical properties of this compound is largely determined by this functional group.
Explanation:
The nitrogen group is considered mixed because it is composed of elements of equally different classifications of metal, non-metal, and metalloids. The group contains the nonmetals nitrogen (N), and phosphorus (P), the metalloids arsenic (As) and antimony (Sb), and the metals bismuth (Bi) and Moscovium (Mc).
