JEE Mains · Chemistry · STD 12 - 7. Alcohol, phenol and ethers
\(4.7\) g of phenol is heated with Zn to give product X. If this reaction goes to \(60\%\) completion then the number of moles of compound X formed will be _______ \(\times 10^{-2}\). (Nearest Integer) (Given molar mass in g mol\(^{-1}\): H:1, C:12, O:16)
- A 2
- B 3
- C 4
- D 5
Answer & Solution
Correct Answer
(B) 3
Step-by-step Solution
Detailed explanation
The chemical reaction of phenol with zinc dust is given by: \(C_6H_5OH + Zn \xrightarrow{\Delta} C_6H_6 + ZnO\) Product X is benzene (\(C_6H_6\)). Molar mass of phenol (\(C_6H_5OH\)) = \(6 \times 12 + 6 \times 1 + 16 = 94\) g mol\(^{-1}\) Number of moles of phenol taken =…
