17. The oxidation number of sulphur in $S _8, S _2 F _2, H _2 S$ respectively, are
(1999)
(a) $0,+1$ and -2
(b) $+2,+1$ and -2
(c) $0,+1$ and +2
(d) $-2,+1$ and -2
Show Answer
Answer:
Correct Answer: 17. (a)
Solution:
In $S_s$, oxidation number number of S is 0, elemental state.
In $S_2F_2$, F is in -1 oxidatoin state, hence S is in +1 oxidation state.
In $H_2S$, H is in +1 oxidation state, hence S is in -2 oxidation state.
