Question

Given the following equations: (i) B2+ + C --> B + C2+ doesn't go (ii) D+ B2+ --> D2+ + B (iii) 2 A3+ + 3D --> 2 A+ 3 D2+ doesn't go Arrange the elements A, B, C, and D from the strongest to weakest reducing agent. goes

Answer 1

27 b. Analysing all the reactions one by one B + C Bt C this vecaction does not go, that means c cannot reduce B 2t to B. This in twen means C has greater tendency to undergo veeduction than B. Therefore, B is vá stronger vreducing agent thane. 4) D+B2 D² + +B This veeaction goes, that means Dican reduce B2+ to B. Therefore. Dis a stronger reducing agent than B. liji) 243*+ 3D -> 2A + 3024 This reaction does not go, that means D cannot reduce A 3+ to A. This is turn

means D has a greater tendency to undergo reduction than A. Therefore, Ais a stronger reducing agent than D. Therefore arranging the elements the strongest to weakest reducing agent A>D>B>C
