Organic Chemistry
An organometallic cyclic compound (E; C6H11MgBr) was synthesized by one of my PhDscholars followed by magnesium in dry ether which was further react with butanal to yielda macromolecule alcoholic compound (F) after mild acidification. Prolonged treatment of
F with an equivalent amount of hydrogen bromide to 1-bromo-1-butylcycloheptane (G).
Write the structures of (E) and (F), and explain how (G) is obtained from (F).
Organic Chemistry
A current is forced through a cell consisting of two platinum electrodes in which each is immersed in a solution of CuSO4 and H2SO4. During the process copper is deposited at the cathode while evolution of oxygen occurs at the anode. The standard potential (Eo) for the reaction occurring at cathode and anode are 0.34V and 1.23V respectively.
(i) Write down the chemical equation for both the cathodic and anodic reactions.
(ii) What is the overall reaction and determine the theoretical decomposition potential?
(iii) Estimate the potential required for the operation of the cell if an additional 0.5V is applied to overcome the resistance of the cell to the current.
