All members share the same general formula.

17
Q

What is an isomer?

A

Compounds with the SAME MOLECULAR formula but different structural formulas.

Example: Compounds with the formula C4H10 but different structures.

18
Q

What do hydrocarbons produce when they burn completely in oxygen?

A

Carbon dioxide and water.

This process is known as complete combustion.

19
Q

What occurs during incomplete combustion of hydrocarbons?

A
