U2: Organic Molecules

Front

What are organic molecules?

Back

Organic molecules are compounds that contain carbon and are typically associated with living organisms. They often include carbon-hydrogen (C-H) bonds.

Front

Why is it important to recognize organic molecules?

Back

Recognizing organic molecules is important because they can transfer energy when they react with oxygen.

Front

What indicates that a molecule is organic?

Back

The presence of carbon to hydrogen bonds in a molecule indicates that it is organic.

Front

What is an example of an inorganic molecule?

Back

Carbon dioxide (CO2) is an example of an inorganic molecule.

Front

How does the number of carbon-carbon or carbon-hydrogen bonds affect energy transfer?

Back

Generally, the more carbon-carbon or carbon-hydrogen bonds a molecule has, the more energy it can transfer when it reacts with oxygen.

Front

What is the primary element found in organic molecules?

Back

Carbon is the primary element found in organic molecules.

Front

What are hydrocarbons?

Back

Hydrocarbons are organic compounds consisting entirely of hydrogen and carbon.

Front

What role do functional groups play in organic molecules?

Back

Functional groups are specific groups of atoms within molecules that determine the characteristics and chemical reactivity of those molecules.

Front

What is the difference between saturated and unsaturated hydrocarbons?

Back

Saturated hydrocarbons contain only single bonds between carbon atoms, while unsaturated hydrocarbons contain one or more double or triple bonds.

Front

What is a common property of organic molecules?

Back

Organic molecules often have low melting and boiling points compared to inorganic molecules.
