EXPERIMENT 9: SYNTHESIS OF DIPHENYLACETYLENE Objective: Complete the two-step halogenation/elimination reaction sequence that converts an alkene (trans- stilbene) to an alkyne (diphenylacetylene) PRELAB NOTEBOOK: In the laboratory notebook, write the overall experimental objective, chemical equation(s), reaction mechanism. draw a diagram or outline of the procedural steps, and complete the chemical safety table for all chemicals. 1. Does this elimination process occur via an E1 or E2 mechanism? Justify your answer by explaining the specific factors that differentiate when E1 versus...

here is the procedure if needed
EXPERIMENT 8: BROMINATION OF TRANS-STILBENE glacial acetic acid Objective: Execute first step of two-step sequence to transform an alkene into an alkyne via a dihalide intermediate and use infrared spectroscopy to identify functional groups PRELAB NOTEBOOK: In the laboratory notebook, write the overall experimental objective, chemical equation(s), reaction mechanism (consider all possible stereoisomers), draw a diagram or outline of the procedural steps, and complete the chemical safety table for all chemicals. 1. Why is...
