(a) 1 only
(b) 1 and 2 only
(c) 1 and 3 only
(d) 1, 2, and 3

Answer is D. 1,2 & 3.

Explanation:

Note that,

* The generic name of a drug is very important because, it will show the chemical name name of the drug when it was first discovered, this will describe the molecular and atomic structure of the drug.

*The contraindication explains the specific situations when a drug should not be used because it may be harmful to the user.

*The user dose shows the quantity of a drug which must be used at a particular point in time.

These three things must be provided before a drug can be approved by the US food and drug administration.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh
