3 isomers:
(E)-1,2-diisopropylethene
(Z)-1,2-diisopropylethene
1,1-diisopropylethene
What is the order of stability of these three isomers based on their steric energies? and Why?
Also, the order of increasing C=C-C bond angle of these three isomers seem to be: 1,1 isomer < E isomer < Z isomer. Why is that?
