Questions & Step-by-Step Solutions

Which of the following compounds is the most acidic?
  • Step 1: Understand what acidity means. Acidity refers to how easily a compound can donate a proton (H+).
  • Step 2: Identify the types of bonds in the compounds. Look for single, double, or triple bonds.
  • Step 3: Know that sp hybridization (found in triple bonds) makes a carbon atom more acidic than sp2 (double bonds) or sp3 (single bonds).
  • Step 4: Compare the compounds given in the question. Look for the one with a carbon atom that is sp hybridized.
  • Step 5: Conclude that propyne, which has a triple bond, is the most acidic because it has sp hybridization.
