To date, I have not seen a single CIE, AQA, Edexcel or OCR, reference or endorsed, book that mentions this reaction (believe me, I've done my reading!). I found it on the internet when I first bumped into the MCQ.Actually in our class we have very well studied about H2 and its reducing ability. The fact is CIE are too buzzed to even correct the marking scheme, God knows whats up with them.
