  • question_answer
    Assertion: RBr reacts with \[AgN{{O}_{2}}\] to give nitroalkane.
    Reason: Silver nitrite (\[AgN{{O}_{2}}\]) is an ionic compound, therefore the negative charge on nitrogen is the attacking site.

    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: C

    Solution :

    Silver nitrite is a covalent compound and the bond between Ag - O is covalent. Therefore, it does not have a negative charge on the oxygen atom. Hence, the nucleophillic attack occurs through the lone pair on nitrogen forming nitroalkanes \[\left( R-N{{O}_{2}} \right)\].
