Derive butanol by starting with Ethanol. You can only use ethanol as a organic compound.
Ethanol is a famous organic compound which is used to synthesis more organic compounds. There are four carbon atoms in butanol molecule. Both ethanol and butanol are alcohol compounds. When we prepare butanol from ethanol, we have to double the number of carbon atoms.
Now, we study the conversion step by step
Ethanol and PCC react to give ethanal(aldehyde).
Ethanal and dilute NaOH or KOH react with heating to form aldol product.
With H2/ Ni, alkene group(double bond) becomes into alkane group and aldehyde group becomes to a alcoholic group.
