PLEASE ANSWER ALL QUESTIONS
Question 5 The reaction below occurs via SN2 and E2 reaction mechanisms. The question only requires you to address the E2 reaction only. For the E2 reaction: Use Newman projections to show the relationship between the leaving group and the beta-hydrogen on the carbon labeled with the asterisk ("). 1. If the leaving group and the beta-hydrogen on the carbon labeled with the asterisk (1) are not in the correct orientation, show the result of the...

2. For each of the following compounds, 1) write the formal oxidation state of the transition metal and 2) the corresponding number of d electrons. 3) State whether or not each one is likely to be stable enough to be characterized. (a) [Re(CO)5] (b) [Cr(η6 -C6H6)2] (c) [Mo(CO)3(PPh3)3] (d) [Fe(η2 -C2H4)(CO)4] (e) [Zr(η5 -C5H5)Cl(OH)] (f) [Co(η5 -C5H5)2] 3. Identify the first-row transition metal (M) that follows the 18-electron rule for each of the following compounds (show how you arrived at...
