Hydrocarbons and Organic Compounds

Front

What is an organic compound?

Back

An organic compound is any of a large class of chemical compounds whose molecules contain carbon, with the exception of carbides, carbonates, cyanides, and carbon oxides.

Front

What are hydrocarbons?

Back

Hydrocarbons are organic compounds that contain only carbon and hydrogen.

Front

What are the main classes of hydrocarbons?

Back

The main classes of hydrocarbons are aliphatic (alkanes, alkenes, alkynes), cyclic (cycloalkanes, cycloalkenes, cycloalkynes), and aromatic (arenes).

Front

What is the general formula for alkanes?

Back

The general formula for alkanes is C_nH_(2n+2).

Front

What is the general formula for alkenes?

Back

The general formula for alkenes is C_nH_(2n).

Front

What is the general formula for alkynes?

Back

The general formula for alkynes is C_nH_(2n-2).

Front

What is isomerism?

Back

Isomerism is when molecules have the same molecular formula but different structural arrangements.

Front

What are saturated hydrocarbons?

Back

Saturated hydrocarbons are hydrocarbons that contain only single bonds between carbon atoms.

Front

What are unsaturated hydrocarbons?

Back

Unsaturated hydrocarbons are hydrocarbons that contain at least one double or triple bond.

Front

What is the difference between aliphatic and aromatic hydrocarbons?

Back

Aliphatic hydrocarbons are open-chain and non-aromatic, while aromatic hydrocarbons contain one or more rings with delocalized π electrons.
