Summery : Here an diels alder
reaction HOMO And LUMO interaction is most important . When these
interaction is absent or orbital energy of HOMO and LUMO are same
then reaction is not take palce. Reaction occure in an thermal
condition.

1. It is hard to get the bars to be parallel in this experiment. Explain why the bars tend to be so wiggly That happens because there is not match friction between the glass plates and it makes it hard to move them gradually relatively to each other, plus the surfaces of the glass plates are not entirely even which makes the friction vary in different areas of the glass plates and their movement...
