What is the general molecular formula of the products obtained on heating lanthanoid (Ln) with sulphur?

A

`LnS`

B

`LnS_(3)`

C

`Ln_(3)S_(2)`

D

`Ln_(2)S_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
When lanthanoids (Lu) are heated with sulphur , then `Ln_(2)S_(3)` are formed their sulphides `(Ln_(2)S_(3))` are highly stable because Ln is `+3` oxidation state.
