I suggest to take a pen and a paper in hand and atleast answer some question on paper and then tell me was it easy or not.

Believe me, on CSS-Forum or seeing superficially the old papers is far too different from solving it on the day.

I ask the answer of 1st part of the paper.
Use internet and everybook and if you find the answer please let me know.

Similarly Oxidise a 2ndry Alcohol to Aldehyde.....plz.
