The electronic, identified by quantum numbers n and l, (i) `n = 4, l = 1`, (ii) `n = 4, l = 0`, (iii) `n = 3,l = 2`, (iv) `n = 3, l = 1` can be placed in order of increasing energy, from the lowest to highest, as

Options

A. (iv) lt (ii) lt (iii) lt (i)
B. (ii) lt (iv) lt (i) lt (iii)
C. (i) lt (iii) lt (ii) lt (iv)
D. (iii) lt (i) lt (iv) lt (ii)

Answer

A

Explanation

Higher is the value of `(n+l)` more is the energy level of orbital. If `(n+l)` is same lower value of n decides lower energy level.
