An aldol condensation reaction using the reagents acetone and benzaldehyde, in the presence of sodium hydroxide was used to produce dibenzylacetone. Give a detailed NMR analysis for the product (address the issue of double bond stereochemistry; 3J values are sensitive to double bond geometry see diagram below).
