Give reason for the following : (i) (CH_(3))_(3)C-O-CH_(3)underset("ether")overset('Anhydrous HI")(rarr) CH_(3)I+(CH_(3))_(3)COH (ii) (CH_(3))_(3)C-O-CH_(34)overset(HI(aq.))(rarr)(CH_(3))_(3)Cl+CH_(3)OH (iii) Ethers possess a net dipole moment even if they are symmetrical in structure. (iv) Dimethyl ether is completely miscible with water but diethyl ehter is soluble in water to a small extent. (v) The C-O-C bond angle in ether is higher than H-O-H angle in water though oxygen is sp^(3)- hybridized in both these cases. (vi) Why are ethers relativelyinert compounds ?

Assertion (A) : The C-O-C bond angle in thers is slightly less than tetrahedral angle. Reason (R ) : Due to the repulsive interaction between the two alkyl groups in ethers

  • (A) The C-O-C bond angle in ethers is higher than H-O-H bond angle in water. (R ) Oxygen is sp^(3) - hybridized in both ethers and water.

    A
    If both (A) and (R ) are correct and (R ) is correct explanation of (A ).
    B
    If both (A ) and (R ) are correct but (R ) is not correct explanation of (A ).
    C
    If (A) is correct but (R ) is incorrect
    D
    If (A) is incorrect but (R ) is correct.

  • Assertion: The C–O-C bond angle in ethers is higher than H-O-H bond angle in water. Reason Oxygen in both ethers and water is sp hybridized.

    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.

  • Assertion (A): The C-O-C bond angle in eithers is slightly less than tetrahedral angle. Reason (R ): Due to the repulsive interaction between the two alkyl groups in ethers.

    A
    Both Assertion (A) and Reason (R ) are correct statements, and Reason ( R) is the correct explanation of the Assertion (A)
    B
    Both Assertion (A ) and Reason ( R) are correct statements, but Reason ( R) is not the correct explanation of the Assertion (A)
