Question:
In an organic chemistry laboratory, a student is performing a reaction to synthesize a compound. The reaction involves the conversion of an alcohol into an alkene using a dehydration process. The student chooses to use concentrated sulfuric acid (H2SO4) as the catalyst for this reaction. However, during the reaction, the student notices that another product is formed along with the desired alkene.
(a) What is the likely identity of the unexpected product formed during the reaction? Explain your answer.
(b) Provide a plausible explanation for the formation of the unexpected product and suggest a modification to the reaction conditions that would favor the desired alkene as the major product.
