I need help in learning how to draw organic substances. For example- Diethyl ether. As well, what is meant by drawing the isomer of the structural formula?

Organic Chemistry: Alcohols

Hi, I need some assistance with this organic chemistry concept. Could you show me how to draw all the alcohols that have the molecular formula C5H11OH. I also need assistance assigning the names to each compound and explaining if they are primary, secondary, or tertiary alcohols.
