some additional notes:

OH is a functional group known as alcohols

​propane and methane are examples of hydrocarbons

groups substituted into hydrocarbon chains are known as functional groups

example: esters ( O=C-O) are used in chemical scents in flavors; this is a functional group that can be substituted into a hydrocarbon chain/compound

-EXAMPLES OF OXYGEN ALLOTROPES= DIOXYGEN/OZONE

-EXAMPLE OF NITROGEN ALLOTROPE= DINITROGEN

-EXAMPLES OF SULFUR ALLOTROPES= ALPHA-SULFUR(EXIST AT LOWER TEMP.) AND BETA-SULFUR (EXIST AT HIGHER TEMP--95.5 CELSIUS)

-DIFFERENT ALLOTROPES CAN EXIST UNDER DIFFERENT CONDITIONS, SUCH AS TEMPERATURE

-ANOTHER EXAMPLE: DIAMONDS ARE AN ALLOTROPHIC FORM OF CARBON THAT CAN FORM GIANT MOELECULAR SOLIDS
