Functional Groups and Characteristics

Functional groups define the chemical reactivity and properties of organic molecules.
They influence specific reactions in organic compounds.

Structure of CH3(CH2)4OH

C2 in CH3(CH2)4OH has two hydrogen atoms bonded.

Cyclooctane Structure

Cyclooctane is composed of eight carbon atoms arranged in a cyclic structure, forming a non-aromatic ring.

Anti-inflammatory Drugs

Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly recognized as anti-inflammatory agents.

Hydrogen Atoms in Lindane

Carbon C1 has 2 hydrogen atoms.
Carbon C2 has 2 hydrogen atoms.
Carbon C3 has 1 hydrogen atom.
Carbon C4 has 1 hydrogen atom.
Carbon C5 has 2 hydrogen atoms.

Properties of Ethanol

Physical properties and reaction types of ethanol are determined by its functional group, particularly the hydroxyl (-OH) group.

Unreactive Compounds

Alkanes are known to be notoriously unreactive, typically requiring harsh conditions to react.

Aromatic Hydrocarbons

Aromatic hydrocarbons, such as benzene, contain a six-membered carbon ring with three alternating double bonds.

Functional Group in Ethanol

The functional group present in ethanol is the hydroxyl group (-OH), which classifies it as an alcohol.

Common Hydrocarbons

Alkanes, saturated hydrocarbons containing only carbon and hydrogen, are the most common types of compounds.

Test your knowledge of organic chemistry by completing skeletal structures and identifying functional groups. Convert skeletal structures to complete structures with all carbon and hydrogen atoms drawn, and lone pairs on heteroatoms. Also, count the number of hydrogen atoms bonded to indicated carbons in various drugs.
