MCQ
Which of the following elements does not show disproportionation tendency?
- ACl
- BBr
- CF
- DI
✓
Answer
- F
Explanation:
Being the most electronegative element, F can only be reduced and hence it always shows an oxidation number of-1. Further, due to the absence of d-orbitals, it cannot be oxidized and hence it does not show +ve oxidation numbers. In other words, F cannot be simultaneously oxidized as well as reduced and hence does not show disproportionation reactions. Thus, option (c) is correct.
