NEET · Chemistry · STD 12 - 7. Alcohol, phenol and ethers
Reaction of phenol with chloroform in presence of dilute sodium hydroxide finally introduces which one of the following functional group ?
- A \(-COOH\)
- B \(-CHCl_2\)
- C \(-CHO\)
- D \(-CH_2Cl\)
Answer & Solution
Correct Answer
(C) \(-CHO\)
Step-by-step Solution
Detailed explanation
Reaction of phenol with chloroform in presence of dilute sodiute sodium hydroxide finally introduces aldehyde \(-CHO \) functional group and hydroxy group at-ortho position. The reaction is known as Reimer-Tiemann reaction. \(C_{6} H_{5} O H \frac{a q^{N a O H}}{C H C l_{3}} 2-O H-C_{6} H_{4}-C H O\)
