Sn2 br vs cl
Web8. How many moles of Br– and Cl– are you weighing out for this part of the experiment? Since they are to make an equimolar mixture of Br– and Cl–, calculating the number of moles of one is sufficient. # moles of Br– = 17.5 g ammonium bromide ÷ 97.96g/mol = 0.178 moles # moles of Cl– = 9.5 g ammonium chloride ÷ 53.50 g/mol = 0.178 ...

Web27 Apr 2012 · So, in case of of chloroform, the THREE -Cl actually contribute to the dipole moment as if it were just ONE -Cl. However, in case of DCM, the TWO -Cl contribute as if there were 2cos(54.9deg.) -Cl = 1.15 -Cl. In summary, using a bit of vector algebra: IN CHCl3 = Dipole eqv. to 1 -Cl IN CH2Cl2 = Dipole eqv. to 1.15-Cl WebBecause of the two major problems for chlorination: the lack of selectivity and multi-substitution, chlorination is not useful as a synthesis method to prepare a specific alkyl …
WebWhat was done. Nine alkyl halides were tested under SN1 and SN2 conditions. The alkyl halides varied by leaving group (Cl- and Br-) and also by substrate structure (1° vs 2° vs 3° vs alkene vs aromatic). The SN1 solution was silver nitrate in ethanol and the SN2 solution was sodium iodide in acetone. Each student was assigned three of the ... Web23 Apr 2013 · Being that Cl is more electronegative than Br, Cl is less willing to give up those electrons as compared to Br. Now as far as leaving groups go, because Br is the …
