Question

Correct order of ionic radii is
O Ti4+ <Mn7+
O 37cr <35c1
OK->cr
O p3+>p5+​

Answer 1

Answer:

Ionic radii of P

3+

>P

5+

More is the positive charge smaller the size.

ionicradii∝

charge

1

in case of Ti

4+

& Mn

7+

⟶Mn

7+

will be smaller

In

35

Cl

−

and

37

Cl

−

⟶ ionic radii remains same for both.

as no. of e

−

& no. of p

+

remains same in K

+

and Cl

−

, K

+

will be smaller as cations are smaller in size than anions.

Hence answer is D.
