Assertion: `Tt^(3+)` salts are coloured whereas `Ti^(4+)` salts are white. `Ti^(3+)` is less stable than `Ti^(4+)`

A

Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation of Statement -1

B

Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation of Statement-1

C

Statement-1 is True, Statement-2 is false

D

Statement-1 is False, Statement-2is True

Text Solution

Verified by Experts

Correct explanation. Ti(III) salts have one unpaired electron in d-subshell `(3d^(1))` whereas Ti(IV) salts have no electron in the d-sbushell `(3d^(0))`.

  • Assertion: Ti^(3+) salts are coloured whereas Ti^(4+) salts are white. Reason: Ti^(3+) is less stable than Ti^(4+)

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

  • Ti^(3+) is purple, while Ti^(4+) is colourless, because

    A
    there is no crystal field effect in `Ti^(4+)`
    B
    The energy difference between eg and `t_(2g)` orbitals of `Ti^(4+)` is quite high and hence, does not fall within the visible region
    C
    `Ti^(4+)` had `3d^(0)` configuration
    D
    `Ti^(4+)` is a very small cation when combated to `Ti^(3+)` and hence, does not absorb any radiation.

  • Ti^(2+) is purple while Ti^(4+) is colourless because

    A
    there is no crystal field effect in `Ti^(4+)`
    B
    `Ti^(2+)" has "3d^(2)` configuration
    C
    `Ti^(4+)" has "3d^(2)` configuration
    D
    `Ti^(4+)` is a very small cation when compared to `Ti^(2+)` and does not absorb any radiation.
