Phenols do not have an H atom attached to the C atom carrying the OH group. Therefore, their reaction with oxidizing agents is quite different from that of primary. Lecture "Phenols and amines" on Pharmaceutical Chemistry is devoted TEST of KROK 2 Qualitative reaction for phenol is the reaction with bromine water. Test with NaOH and chloroform: a violet colour develops. 4. NHCOCH3 OH NH2 OH NH O OH NH2 N O NH2 HCl, t C - CH3COOH 0 K2Cr2O7 5.

Lidocaine, is a local or topical anesthetic. The Reimer—Tiemann reaction can be altered to yield phenolic acids by substituting the chloroform with carbon tetrachloride. Embed Size px.
Potassium Dichromate Test: 5 ml solution of the extract was taken in a test tube. Sulphuric Acid Test: 1 ml solution of chloroform extract was taken and added.
