How many hydrogen atoms can be attached to carbon B?

Which one of these is an amino group?

Which of these is a phosphate group?

Which of these is a hydroxyl group?

Which of these is a carboxyl group?

Which of these functional groups is characteristic of alcohol?

Which of the functional groups behaves as a base?

Which of these groups plays a major role in energy transfer?

Hydrocarbon Differences

Hydrocarbons can differ in structure: branched, double bonds, or ring formation.
A branched hydrocarbon allows for varied connectivity between carbon atoms.
A hydrocarbon with a double bond exhibits unsaturation, affecting its reactivity.
Ring-structured hydrocarbons present cyclic properties, influencing chemical behavior.

Hydrogen Atom Attachment

Carbon A can attach 3 hydrogen atoms because it has one bond already formed with another atom.
Carbon B can only attach 1 hydrogen atom since it already forms three bonds.

Functional Groups

The amino group is identified as NH2, indicating a basic functional group involved in amino acids.
A phosphate group, essential for energy transfer, is represented by B; notably ATP contains this group.
The hydroxyl group, associated with alcohols, is labeled as D, highlighting its polar characteristics.
The carboxyl group, which can act as both an acid and a base, is represented by F.

Group Characteristics

Alcohols are characterized by the hydroxyl functional group (D).
The amino group (A) acts as a base due to its ability to accept protons.
The phosphate group (B) is crucial in energy transfer processes in biological systems.
The carbonyl group is represented as C, found in various organic compounds, influencing their reactivity and physical properties.
