Question

An ether [a], c5h12o, when heated with excess of hot concentrated hi produced two alkyl halides which when treated with naoh yielded compounds [b] and [c]. Oxidation of [b] and [c] gave a propanone and an ethanoic acid respectively. The iupac name of the ether [a] is:
a.2-ethoxypropane
b.Ethoxypropane
c.Methoxybutane
d.2-methoxybutane

Answer 1

The IUPAC name of the ether [a] is 2-ethoxypropane .

• Propanone is formed due to oxidation of 2- Propanol . Hence [b] is 2- Propanol .
• Ethanoic acid is formed due to oxidation of ethanol . Hence [c] is ethanol .
• Thus the two alkyl halides must be 2- propyl halide and ethyl halide .
• Hence , the ether is [a] 2-ethoxypropane .
