Its structures of compound were characterized based on the interpretation of spectroscopic data including UV, FTIR, NMR, and MS. The compound show a good yield (60,57%). Its melting point observed in the range of 102-103 0 C.en1-acethylnaphthalene2-bromobenzaldehydechalconestudent Paper Post Degree
