Questions and Answers

What is the general formula for alcohols?

The general formula for alcohols is R−OH.

How do primary, secondary, and tertiary alcohols differ based on their structure?

Primary alcohols have the -OH group attached to a carbon bonded to one other carbon, secondary to two, and tertiary to three other carbons.

Define monohydric alcohol and provide its general formula.

Monohydric alcohol is an alcohol with one -OH group, and its general formula is R−OH.

What is a benzylic alcohol?

<p>A benzylic alcohol is an alcohol where the -OH group is attached to a carbon atom on a benzene ring.</p> Signup and view all the answers

Study Notes

Alcohols

  • Alcohols are organic compounds containing a hydroxyl group (-OH) bonded to a saturated hydrocarbon
  • Alcohols are represented by the general formula R-OH, where R is an alkyl group
  • Alcohols can be classified based on the number of -OH groups present

Classification of Alcohols

  • Monohydric alcohols have one -OH group
  • Dihydric alcohols have two -OH groups
  • Trihydric alcohols have three -OH groups
  • Polyhydric alcohols have more than three -OH groups

Classification of Monohydric Alcohols

  • Primary alcohols have the -OH group attached to a carbon bonded to one other carbon atom
  • Secondary alcohols have the -OH group attached to a carbon bonded to two other carbon atoms
  • Tertiary alcohols have the -OH group attached to a carbon bonded to three other carbon atoms

Other Types of Alcohols

  • Allylic alcohols have the -OH group attached to a carbon atom adjacent to a carbon-carbon double bond
  • Benzylic alcohols have the -OH group attached to a carbon atom on a benzene ring
