THis is also known as an alchohol.
a)hydroxyl group
b) amino group
c) phosphate group
d) carboxyl group
A hydroxyl group is an alcohol IF the hydroxyl group is attached to an aliphatic chain. Ring systems in which an OH is attached is not called an alcohol.
1- A. 2-D. 3-A
The correct answer is a) hydroxyl group.
To arrive at the answer, you need to understand the functional groups commonly found in organic compounds. One common functional group found in alcohols is the hydroxyl group (-OH). This group consists of an oxygen atom bonded to a hydrogen atom and is attached to the carbon skeleton of a molecule.
On the other hand, the amino group (-NH2) is found in amines, the phosphate group (PO4) is found in phosphates, and the carboxyl group (-COOH) is found in carboxylic acids.
By understanding the properties and characteristics of different functional groups, you can identify the correct functional group based on the description provided. In this case, an alcohol contains the hydroxyl group, making option a) the correct answer.
