What is the difference between an alcohol and a ketone?

Back

An alcohol contains a hydroxyl group (-OH), while a ketone contains a carbonyl group (C=O) within the carbon chain.

Front

What is a ball and stick model?

Back

A ball and stick model is a molecular model that represents atoms as balls and chemical bonds as sticks, illustrating the 3D arrangement of atoms in a molecule.

Front

What is the process of vaporization?

Back

Vaporization is the process by which molecules transition from the liquid or solid state to the gas state.

Front

What is a structural formula?

Back

A structural formula shows the arrangement of atoms in a molecule, including the bonds between them.
