A mechanism for the reaction of a ketone with semicarbazide

Reference no: EM13690011

Problem- a) Give a mechanism for the reaction of a ketone with semicarbazide to form a semicarbazone

b) Why is sodium acetate added in the preparation of the semicarbazone of bezalacetone

c) Write a structure for the product formed by condensing benzaldehyde with acetophenone

d) Write stereo structures for all possible stereoisomers of bezalacetone and dibenzalacetone. In each system, only one stereoisomer is the actual product. Which isomer is formed and why. Explain

I need help for above questions. Show each steps for the above problems.
