What is the orbital angular momentum of an electron in 'f' orbital ?

Options

A. `(1.5 h)/(pi )`
B. `(sqrt6 h)/(pi)`
C. `(sqrt3 h)/(pi )`
D. `(sqrt3 h)/(2pi)`

Answer

C

Explanation

Orbital angular momentum ,
`mvr = (h)/(2pi ) sqrt(l (l + 1))`
For f- orbital , l = 3
`therefore` Orbital angular momentum ,
mvr = `(h)/(2pi) sqrt(3 (3 + 1)) = (sqrt3h)/(pi )`
