Question

Draw the complete structure of propane. (Draw all hydrogen atoms.) b) Draw the structure of propane in skeleton mode or as a bond-line structure. (Do not draw the hydrogen atoms.)

Answer 1

Propane is a hydrocarbon with the molecular formula C3H8. In the complete structure, all carbon and hydrogen atoms are drawn. In the skeleton mode, only carbon atoms are represented.

Step-by-step explanation:

Propane is a hydrocarbon with a molecular formula of C3H8. In the complete structure of propane, you would draw all the carbon and hydrogen atoms.

In the skeleton mode or bond-line structure of propane, you only draw the carbon atoms as the ends of lines or bends in a line. Hydrogen atoms attached to carbon atoms are not drawn.

To draw the complete structure of propane, you can start by drawing three carbon atoms in a row, each bonded to the required number of hydrogen atoms.
