As far as chemistry is concerned ALKAnes arent oxidised by acidified dichromate, infact they are inert compounds and dont even get oxidised other then combustion and free radical substitutions.......u were confused...actually alkenes are converted to alcohols, this also by reaction with steam at 60atm 350C with H3PO4 catalyst.....

there was a question
About gas present in the exhaust of a car engine in a much greater amount than any
other gas?
A carbon dioxide
B carbon monoxide
C nitrogen
D water vapour

What was the question? i.e was it just the gas present in the exhaust (then the answer is C) or gas that is a product of combustion (then the answer is D)

i do think that they mentioned it as poisonous gas in the exhaust

you mixed up ur questions. There was a question regarding a gas that does not produce poisonous gas when burned. For tht the answer was Hydrogen. and about the car exhaust, they didnt ask for a poisonous gas. It's actually a repeat question frm 2002

And for the car exhaust one as far as I feel the question was which gas produced is most harmful and that's
definitely CO :)
Also asked from my friends they too all did CO :/

I did CO too
As far as I remember it asked the most harmful gas :)
Mostly people just ticked N2 because they thought it was a repeated question

But all we can do is just wait for the marking scheme :)
