10. The following compound was produced in a Diels-Alder reaction. .COOH COOH a) How many sp hybridized carbons are in this molecule? b) Is this molecule chiral? c) Are the carboxylic acid substituents electron donating group or electron withdrawing group? d) Draw the diene and dienophile which would react together to give this product.

How do you draw the diels-alder product for this with stereochemistry? How do you know they are cis?

Can i get help with this problem?

6. Why are the orbitals not aligned in the dienophile LUMO across the double bond? H LUMO

Draw the structure(s) of the product(s) of the following Diels-Alder reaction. Stereochemistry must be shown, and make sure to draw explicit hydrogens around all stereocenters.
