Compound X, C₄H₈O₂, has an unbranched carbon chain. An aqueous solution of X has an approximate pH of 3. Compound Y, C₃H₈O, is a secondary alcohol. X and Y are reacted together in the presence of a little concentrated sulfuric acid to form Z as the major organic product. What is the structural formula of Z?
A(CH₃)₂CHCO₂CH₂CH₂CH₃
BCH₃(CH₂)₂CO₂CH(CH₃)₂
CCH₃(CH₂)₂CO₂(CH₂)₂CH₃
D(CH₃)₂CHCO₂CH(CH₃)₂
✓ Correct answer
B: CH₃(CH₂)₂CO₂CH(CH₃)₂
