(A) H, with Pt (B) NaH (C) Tosyl chloride in pyridine followed by LiAIH (D) CuO and heat 9. Suggest a reasonable synthesis of ethyl isopropyl ether, beginning with alkanes, alkenes or alkyl halides. (2 points)
Explanation / Answer
Alcohols undergo dehydration which means water molecule is removed from the alcohol to form alkene.
2, methyl 2-butanol react with H2SO4 to give 2-methyl 2-butene
