If the orbital angular momentum of iron chloride is `5sqrt6h` then the correct options for this given fact are:

Options

A. `FeCl_(3)`
B. `FeCl_(2)`
C. `Fe_(2)Cl_(6)`
D. None of these

Answer

A

Explanation

Orbital angular momentum per electron `= sqrt(l(l + 1))(h)/(2pi)`
`sqrt(2(2 + 1)) (h)/(2pi)`
`sqrt6 h`
For `Fe^(3+)`
`:.` Total orbital angular momentum in `Fe^(3+)` salt (per molecule) `= 5 sqrt6 h`
