    • What is the functional group present in alcohols?
      -OH (hydroxyl)
    • What is the general structure of alcohols?
      Alkyl group + -OH
    • What is the general structure of carboxylic acids?
      Alkyl group + -COOH
    • What is an example of a carboxylic acid?
      Formic acid (HCOOH)
    • Carboxylic acids are strongly acidic due to the presence of the -COOH group.

      True
    • The carboxyl group in carboxylic acids is -COOH.
    • What is the functional group in carboxylic acids?
      -COOH (carboxyl)
    • What is the general structure of alcohols?
      -R-OH
    • What type of bond is present in the hydroxyl group (-OH)?
      C-O-H
    • The -OH functional group in alcohols is weakly acidic due to its ability to partially donate a proton
    • What suffix is used to name alcohols in the IUPAC system?
      -ol
    • What suffix is used to name carboxylic acids in the IUPAC system?
      -oic acid
    • Steps to name an alcohol
      1️⃣ Identify the parent alkane chain
      2️⃣ Replace the "-ane" ending with "-ol"
      3️⃣ Indicate the position of the -OH group using a number prefix
    • Carboxylic acids contain the functional group -COOH
    • Carboxylic acids have a general structure of an alkyl group attached to the -COOH functional group.
    • The functional group in alcohols is attached to an alkyl group.
    • What is the general structure of alcohols?
      Alkyl group + -OH
    • Match the property with the correct compound:
      Weakly acidic ↔️ Alcohols
      Strongly acidic ↔️ Carboxylic Acids
    • What is the functional group in alcohols?
      -OH (hydroxyl)
    • Carboxylic acids are strongly acidic while alcohols are weakly acidic.

      True
    • Both alcohols and carboxylic acids contain an alkyl group (-R) bonded to a functional group
    • What bonds are present in the carboxyl group (-COOH)?
      C=O and C-OH
    • What is the key difference in acidity between alcohols and carboxylic acids?
      Carboxylic acids are stronger
    • In alcohol nomenclature, the "-ane" ending of the parent alkane is replaced with -ol
