- Which of the following choices correctly represents X in the incomplete reaction mechanism shown in the first photo?Chemistry please show synthesis steps.Curved arrows are used to illustrate the flow of electrons. Follow the arrows and descriptions of the elementary steps to draw all of the intermediates and products involved in this reaction. Include all line-pairs. Ignore any inorganic byproducts.
- Since there are 2 reagents you have a choice for “loading up” one of then to drive a reaction. Briefly explain why “loading up” on one reagents drives the reaction while the other one would decrease the overall yield. The procedure is below and the reaction is attached. Procedure Synthesis of Dibenzalacetone (A) In this lab you will need to determine the amounts of the reactants you will use. We will use 0.0125 moles of acetone. You need to: (1) convert this into a volume in mL, (2) Calculate the number of moles of benzaldehyde needed based on the balanced chemical reaction, (3) Convert the number of moles of benzaldehyde into volume in mL. Your reagent table should reflect your calculated values. Mix the benzaldehyde and acetone based on the volumes from your prelab calculations in a testtube. Add 25 mL of 10% NaOH solution to a 125 mL Erlenmeyer flask along with a stir bar and 20 mL of ethanol. Make sure the temperature of the solution in the flask is below 25 C before…quesition 1; image questions 2; What type of reaction is this?Choose one: bimolecular /homolytic /substitution/initiation/coupling/SN2/additionPls ignore the highlighted part __________ is reduced in thefollowing reaction: Cr2O72- + 6S2O32-+ 14H+→ 2Cr3+ + 3S4O62- + 7H2O
