Question: Which of the following compounds is the most acidic?

Options:

Correct Answer: Propyne

Solution:

Propyne is the most acidic due to the sp hybridization of the carbon atom involved in the triple bond.

Which of the following compounds is the most acidic?

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.
