Question

what is a functional group? give examples of four different functional group​

Answer 1

Answer:

Learning Objective

Describe the importance of functional groups to organic molecules

Key Points

Functional groups are collections of atoms that attach the carbon skeleton of an organic molecule and confer specific properties.

Each type of organic molecule has its own specific type of functional group.

Functional groups in biological molecules play an important role in the formation of molecules like DNA, proteins, carbohydrates, and lipids.

Functional groups include: hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl.

Terms

hydrophobiclacking an affinity for water; unable to absorb, or be wetted by water

hydrophilichaving an affinity for water; able to absorb, or be wetted by water

Location of Functional Groups

Functional groups are groups of atoms that occur within organic molecules and confer specific chemical properties to those molecules. When functional groups are shown, the organic molecule is sometimes denoted as “R.” Functional groups are found along the “carbon backbone” of macromolecules which is formed by chains and/or rings of carbon atoms with the occasional substitution of an element such as nitrogen or oxygen. Molecules with other elements in their carbon backbone are substituted hydrocarbons. Each of the four types of macromolecules—proteins, lipids, carbohydrates, and nucleic acids—has its own characteristic set of functional groups that contributes greatly to its differing chemical properties and its function in living organisms.

Answer 2

Answer:

functional group are specific atoms ,ions or groups of atoms having consistent properties

Explanation:

for example: OH -hydroxyl group characterizes alcohol
