.

A

`1,1,1`

B

`1,2,3`

C

`1,13`

D

`1,3,1`

Text Solution

Verified by Experts

The correct Answer is:
C
For (I) (Ground state )
Total sjpins ` s = + 1/2 - 1/2 =0`
` :.` Spin multiplicity `= ( 2 xx 0) +1=1`
For (II) (singlet excited state )
Total spin ` S= + 1/2 = 1/2 =1`
`:.` Spin multiplicity ` = (2 xx 1) = 1 =3`.

L = sqrt(l(l+1)) (h)/(2pi) On the other hand, m determines Z-component of orbital angular momentum as L_(z) = m ((h)/(2pi)) Hunds rule states that in degenerate orbitals electron s do not pair up unless and until each such orbital has got an electron with parallel spins. Besides orbital motion, an electron also possess spin-motion. spin may be clockwise and anti-clockwise. Both thes spin motions are called two spin states of electron characterised by spin. s = +(1)/(2) and s =- (1)/(2) , respectively. An orbital has n = 5 and its l value is the maximum possible. The orbital angular momentum of the electron in this orbital will be
