Chemistry: Post your doubts here!
10: A. They're coming out unchanged at the end of the reaction so yes. They are. Besides, B is out. Cl is reduced in B. C Light initiates the reaction so has to be the first one. Plus depth is relative to the intensity hence defo 1. D Ag goes from +1 to 0. Left with A. 20: A I've answered... -

etc. Two alkyl groups on the same carbon will give you the ketone. The C=C will split and C=O will be formed with the same R groups. If instead of either of the R groups there was a H present, it would've formed carboxylic acid. Same, C=O and the H oxidised to OH. -

Cleavage occurs and the double bond is split. If the side being split is CH2, it forms CO2+H2O. If it's CHR then it forms COOH. If it's CRR' then it forms a Ketone. Get it? -

As a matter of fact, I do. Gimme a day. I'll gather up all the individual facesheets, merge them and upload them and send you the link. Or, if you want specific topics, let me know and I'll send you those. -

Br2 + 2e <=> 2Br- +1.07 O2 + 4H+ + 4e <=> 2H2O +1.23 The oxygen reaction will go forward, the Bromine reaction will go backwards. Br2(g) will be evolved. -

iv- The decomposition will complete when the plunger stops moving outwards. You'll heat and reheat till the point comes when the plunger stops moving outwards. v- You've to record the volume of gas collected. You've already calculated how much volume of gas a fixed mass of copper carbonate will... -

1.8 relative rate with a varying concentration of H+ means increasing or decreasing H+ doesn't effect the rate so order 0!
