The common question we deal with is Nitrogen monoxide.
SO2 --> SO3 and CO-->CO2 does not take place readily in atmosphere.

16: D as conc. H2SO4 displaces iodine from NaI so it must be a stronger oxidising agent. All others are opposite.
26: Cannot be B as this cannot be oxidised. In A and C only one CHO so will react with 1 mol of HCN.

Assume it gives SO2 as the main product, though its not suprising should a bit of SO3 should form.
Based on syllabus from years ago, a catalyst (vanadium oxide) needed to change SO2 to SO3 during manufacturing of H2SO4

Look for the molecule that can contribute most Cl radicals. Option A.

erm, this one is just as easy to google as to type here.
usually H2O is involved, and we might get (NH4)2SO3

Ok, guys. Its past midnight for me.
Time for me to log off.
If things go well, I might be back for the November batch, perhaps some of you might be kind enough to help them also since you have already ploughed through the questions in your current preparations.
All the best for your papers and your soon-to-be achieved freedom from exams.
