Please do A, B, and C The following SN2 and SN1 reactions involve an acid-base reaction in the first step. Provide the intermediate products of the acid-base reaction and then provide the product(s) of the reaction. Show stereochemistry where appropriate. 1. a) Na NH2 Ph CH3 он KOtBu b) но c) HCI CH3 CH3
SHORT ANSWER: 1.) Explain “Hard versus Soft” acid-base behavior. 2.) Explain, in terms of ΔS & ΔG, why imperfections occur in crystals & be able to describe at least two of the four main types of defects, with a drawing of each. 3.) Describe how electron transfer occurs in either the outer sphere or the inner sphere redox reaction mechanism (choose one OR the other). 4.) Explain how to synthesize the cis and trans isomer of a square planar complex,...
2 examples please Some word problems in this chapter involve one "easy equation", usually found by translating a simple relationship between x and y (like one is twice the other or that they add to a given number). The second linear equation often uses a "rate times quantity formula. This is true for • distance problems (rate.time = distance) • mixture problems (percent concentration amount of solution - amount of concentrate) money problems (value of one item. how many items...

Pb2+ + Ag C. Zn2+ + Mg D. Sn2+ + Ni2+ The general formula for a cycloalkane can be represented by which of the following? a. C,H, C. CH b. C.H2n+2 d. C.H21-2 In a certain reaction AH =-136 kJ and E, = 96...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
