Problem: Consider the following organic substances: ethanol, propane, hexane, and propanol.Which of these molecules contains an OH group?

FREE Expert Solution

To determine the name of the compound, let’s first determine the different functional groups of organic compounds.

Alkane

simplest type of functional group
made up only of carbons and hydrogens single bonded to each other
Example:


Alkene

• with at least one carbon-carbon double bond
 Example:


Alkyne

• with at least one carbon-carbon triple bond
Example:


Alcohol

• contains carbon single bonded with -OH
Example:


Amine

contains at least one carbon single bonded with Nitrogen (-N)
Example:


Aldehyde

• contains a carbon double bonded to an oxygen (=O) and single bonded to a hydrogen (-H)
• terminal functional group (found at the end of the compound)
Example:


Ketone

contains three carbons and the middle carbon is double bonded to an oxygen (=O) 
Example:


Carboxylic Acid

contains a carbon double bonded to an oxygen (=O) and single bonded to an –OH
Example:


Ester

contains a carbon double bonded to an oxygen (=O) and single bonded to an oxygen (-O) and that oxygen is single bonded to another carbon
Example:
