Concept explainers
a) CH3CH=CH2
Interpretation:
Can CH3CH=CH2 exist as pairs of cis-trans isomer is to be stated. If so, the structures of cis-trans pair are to be drawn indicating their geometry.
Concept introduction:
The lack of rotation around carbon-carbon double bonds leads to cis-trans isomerism. The requirement is that both the carbons in double bond should be bonded to different substituents. Compounds that have one of their doubly bonded carbons bonded to identical substituents cannot exist as cis-trans isomers.
To change:
Whether CH3CH=CH2 can exist as a pair of cis-trans isomers and to draw their structures with the geometry.
b) (CH3)2C=CHCH3
Interpretation:
Can (CH3)2C=CHCH3 exist as pairs of cis-trans isomer is to be stated. If so, the structures of cis-trans pair are to be drawn indicating their geometry.

- Shown below is the mechanism presented for the formation of biasplatin in reference 1 from the Background and Experiment document. The amounts used of each reactant are shown. Either draw or describe a better alternative to this mechanism. (Note that the first step represents two steps combined and the proton loss is not even shown; fixing these is not the desired improvement.)
