Hexanoyl Chloride on treatment with excess
Ethyl Magnesium Bromide yields
tertiary Alcohol. In this reaction Hexanoyl chloride is first converted into
intermediate ketone (Octane-3-one), secondly the ketone formed is further reduced to <em>
tert.</em>
Alcohol (3-Ethyloctan-3-ol), The reaction along with mechanism is shown below,
Explanation:
-plants that can absorb copper ions are grown on soil with low grade copper ores.
-the plants are burned and the copper compounds are within the Ash.
-copper ions can be leached from the Ash by adding sulphuric acid, this makes a solution of copper sulphate
-the displacement of scrap iron makes pure copper metals.
