Draw the reaction of benzalacetophenone with bromine Draw the reaction of benzalacetophenone with hydrogen peroxide
2) The hydrogen peroxide is added slowly to reduce the peak concentration of bromine (Br2) generated. What effect does lowering the bromine concentration have on the rate of the main reaction? Group of answer choices A) The effect on the reaction rate can not be determined. B) A lower bromine concentration makes the reaction faster.. C) A lower bromine concentration makes the reaction slower. D) A lower bromine concentration has no effect on the reaction rate.
(Part A) Hydrogen peroxide is unstable and decomposes readily: 2H2O2(aq) → 2H2O(l) + O2(g) This reaction is accelerated by light, heat, or a catalyst. The concentrations of aqueous hydrogen peroxide solutions are normally expressed as percent by mass. In the decomposition of hydrogen peroxide, how many liters of oxygen gas can be produced at STP from 26.8 g of a 7.50% hydrogen peroxide solution? (Part B) What volume of bromine (Br2) vapor measured at 100.°C and 700. mmHg pressure would...

Draw the structure resulting froma reaction of 1. diborane (B2H), followed by 2. alkaline hydrogen peroxide (NaOH/H2O,) with the following alkene. . Use the wedge hash bond tools to indicate stereochemistry where it exists. If a group is achiral, do not use wedged or hashed bonds on it If the reaction produces a racemic mixture, just draw one stereoisomer
