Knowledge Check

  • Assertion (A) : The elements which give the greatest number of oxidation states occur in or near the middle of the series. Reason (R) : The lowest common oxidation state of transition elements is +2.

    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).
    C
    Assertion (A) is correct, but Reason (R) is incorrect statement.
    D
    Assertion (A) is incorrect, but Reason (R) is correct statement.

  • The variability of oxidation states of transition elements arises out of:

    A
    incomplete filling of d-orbitals
    B
    oxidation states differing by a unit two
    C
    greater stability of lower oxidation state
    D
    greater stability of higher oxidation state

  • False statement about the trent in oxidation states of transition element is :

    A
    There exists a general trend of lesser number of oxidation states at each end of the series and higher number in the middle
    B
    There is reduced tendency of higher oxidation states towards the end of the series
    C
    The stability of the higher oxidation states decreases going down the group
    D
    the highest oxidation stetes are oftern stabilized in the oxides and fluoride compounds.
