Options
- Aa-q, b-r, c-p, d-r
- Ba-q, b-r, c-s, d-p
- Ca-r, b-s, c-p, d-q
- Da-r, b-p, c-q, d-s
Correct answer
B. a-q, b-r, c-s, d-p
Step-by-step solution
Short reasoning: - (a) ( CO +2 H ₂ CH ₃ OH ) (methanol) over ( ZnO - Cr ₂ O ₃ q ). - (b) ( C ₆ H ₁₂ O ₆ )-Zymase ( ) ethanol (+ CO ₂ r ). - (c) Ethanol + conc. ( H ₂ SO ₄ ) at (443 ~K ) dehydration to alkene ( ( CH ₂= CH ₂ ) s ). - (d) Ethanol + conc. ( H ₂ SO ₄ ) at (413 ~K ) etherification to diethyl ether ( ( C ₂ H ₅- O - C ₂ H ₅ ) p ).
