Give a mechanism for the preparation of the appropriate benzalacetophenone using ~e_ aldehyde that you selected in this experiment. "(c 2. draw the structure of the cis and trans isomers ofthe compound that you prepared. did you obtain the trans isomer?

Following reaction shows the reaction of Acetephenone with benzaldehyde derivative. Among corresponding chalcones formed the trans isomer is more favored and is obtained because of its low energy as compared to cis isomer which has higher energy due to steric interactions between the substituents.
