If the given four electronic configuration
(i) n=4, l=1
(ii) n=4, l=0
(iii) n=3, l=2
(iv) n=3, l=1
ara arranged in order of increasing energy, then the order will be-

Options

A. `ivltiiltiiilti`
B. `iiltiiiltiltiv`
C. `iltiiiltiiltiv`
D. `iiiltiltivltii`

Answer

A

Explanation

For (i), (ii), (iii) and (iv), the orbitals of given quantum numbers are 4p, 4s, 3d and 3p. The order of increasing energy of the orbitals is `3p lt 4s lt 3d lt 4p`.
