  1. Question 1

    Q1. The formation of an acetal is a common method to protect carbonyl groups. Which reactants are required to form 1,1-diethoxyethane?

    • A) One mole of aldehyde and one mole of alcohol
    • B) One mole of ketone and two moles of alcohol
    • C) One mole of propanone and two moles of ethanol
    • D) One mole of ethanal and two moles of ethanol

    Answer: One mole of ethanal and two moles of ethanol

    Explanation: Acetals form when an aldehyde reacts with two moles of alcohol using dry HCl. Option C fails because ketones form ketals.
