Oxidation numbers `+2` and `+4` are exhibited by
`(i) Si`
`(ii) Ge`
`(iii) Sn`
`(iv) Pb`

A

`(i), (ii), (iii), (iv)`

B

`(ii), (iii), (iv)`

C

`(i), (ii), (iii)`

D

`(iii), (iv)`

Text Solution

Verified by Experts

The correct Answer is:
B
Like `C`, the most stable oxidation state of `Si` is `+4`. The remaining elements of group `14 (Ge, Sn`, and `Pb)` exhibit two different oxidation numbers of `+2` and `+4` in their compounds due to inert pair effect.
