2.5.3 Alcohols and Carboxylic Acids

• What is the name of the alcohol with one carbon atom?

  Methanol
• The general formula for carboxylic acids is R-COOH.

  True
• Alcohols have higher boiling points than their corresponding alkanes due to hydrogen bonding.
• Carboxylic acids have higher boiling points than alcohols with the same number of carbon atoms.


  True
• What is the functional group in carboxylic acids?

  Carboxyl
• The general formula for carboxylic acids includes the carboxyl group (-COOH).


  True
• Alcohols contain the hydroxyl group (-OH).


  True
• Higher alcohols are less soluble in water than lower alcohols.


  True
• Lower alcohols are soluble in water
• Alcohols are named by adding "-ol" to the stem
• What is the general formula for alcohols?

  R-OH
• The general formula for alcohols is R-OH
• The carboxyl functional group in carboxylic acids is represented as -COOH

  True
• The hydroxyl group in alcohols makes them acidic

  True
• Alcohols are weakly acidic due to the presence of the hydroxyl group


  True
• Carboxylic acids have higher boiling points than alcohols due to stronger intermolecular hydrogen bonding.
• The boiling point of carboxylic acids is higher than that of corresponding alcohols.
• Formic acid is used as a preservative and a disinfectant.
• Acetic acid is used in vinegar as a food preservative.


  True
• Match the compound with its use:

  Carboxylic Acids ↔️ Food preservatives

  Alcohols ↔️ Fuels
• Carboxylic acids are named by adding "-oic acid" to the stem name.


  True
• The general formula for alcohols is R-OH, where R represents an alkyl group.
• What makes alcohols weakly acidic?

  Hydroxyl group
• Lower alcohols are soluble in water.
• Alcohols are weakly acidic
• Alcohols have higher boiling points than corresponding alkanes
• The boiling points of carboxylic acids are higher than those of corresponding alcohols
• The general formula for alcohols is R-OH.


  True
• Carboxylic acids are organic compounds containing a carboxyl group attached to a carbon atom.
• Alcohols are acidic.

  False
• Lower alcohols are soluble in water due to their hydroxyl group.
• The functional group in alcohols is the hydroxyl group (-OH).
• What is the alkyl group in the general formula for alcohols?

  R
• What functional group is present in carboxylic acids?

  Carboxyl
• Why are alcohols weakly acidic?

  Hydroxyl group
• Alcohols are strongly acidic due to the hydroxyl group.

  False
• What is the functional group in carboxylic acids?

  Carboxyl group (-COOH)
• Ethanol has the formula C₂H₅OH.


  True
• Match the general formula with the correct organic compound:

  R-OH ↔️ Alcohol

  R-COOH ↔️ Carboxylic Acid
• In the general formula for alcohols, R represents an alkyl group.
