What would have been the best starting materials for the
synthesis of R-2-ethoyxbutane?
3. A student wanted to make R-2-ethoxybutane, using the Williamson ether synthesis. He remembered that the Williamson synthesis involves an SN2 displacement, which takes place with inversion of configuration. He ordered a bottle of S-2-butanol for his chiral starting material. He also remembered that SN2 goes best on primary halides, so he made ethyl bromide and S-2-sodiumbutoxide. After warming these reagents together, he obtained an excellent yield...

If anyone has Matlab, help me with problem e and f.
Thank you.
Design by Synthesis: It is possible to design the PID so that the overshoot of the feedback system would be zero, furthermore, the feedback system would behave as a first order system. This is done by noting the PID transfer function: 3. PID Controller Plant Gp (s) R(s) C(s) s2+s+1 Note in the above KPK and Ki/Kp may be chosen so that the numerator of the PID...
