  • question_answer
    Assertion : Dimethyl ether and diethyl ether are soluble in water.
    Reason : As the molecular mass increases, solubility of ethers in water decreases.

    A) Assertion and reason both are correct statements and reason is correct explanation for assertion.

    B) Assertion and reason both are correct statements but reason is not correct explanation for assertion.

    C) Assertion is correct statement but reason is wrong statement.

    D) Assertion is wrong statement but reason is correct statement.

    Correct Answer: B

    Solution :

    The solubility of lower ethers in water is due to the formation of H-bonds between water and ether molecules. As the molecular mass increases, the solubility of ethers in water decreases due to corresponding increase in the hydrocarbon portion of the molecule.
