    Statement 2: In halides of transition metals, the ionic character decreases with increase in atomic mass of the halogen.

    A)  Statement-1 is false, Statement-2 is true.

    B)  Statement-1 is true, statement-2 is true and statement-2 is correct explanation for statement-1

    C)  Statement-1 is true, Statement-2 is true and statement-2 is NOT correct explanation for statement-1

    D)  Statement-1 is true, Statement-2 is false.

    Correct Answer: B

    Solution :

     Anhydrous copper (II) chloride is a covalent while anhydrous copper (II) fluoride is ionic in nature because in halides of transition metals, the ionic character decreases with increase in atomic mass of the halogen. Fluorine being the most electronegative, forms ionic salt with copper.
