[MaXiiMo]

I DON'T know how I'm going to get an A in this shit. I don't even think I'll get a B
My average score when I practice the past papers is just about 25 out of 40
How are you guys doing? What do you expect?

mcq 22: for a quick answer, only D shows cis-trans isomerism and when any of its hydrogen atoms of methyl groups would be substituted by Cl, it will show chirality...none of the other options show cis-trans isomerism and chirality after substitution.

mcq 21: hot KMnO4 ruptures the double bond. And remember three rules...if two Hydrogens are attached to C=(carbon double bond) , CO2 is produced, if one R group and one hydrogen is attatched to C= ... carboxylic acid is produced,. if two R groups are attached, ketones are formed...

Apply these rules,

On each carbon double bond , one hydrogen atom and one R group is attached, so two carboxylic acids will be produced...

CH3CH2COOH

and

HOOCCH2COOH (dicarboxylic coz OH group will also be oxidised)!!!!
