What is the meaning of O nitrophenol?
1 : a nitro derivative of phenol: such as. a : a yellow crystalline compound O2NC6H4OH used chiefly in organic synthesis. — called also ortho-nitrophenol. b : a colorless to yellowish isomeric compound O2NC6H4OH used chiefly as an acid-base indicator, as a fungicide, and in organic synthesis.
Is 4-nitrophenol basic or acidic?
4-nitrophenol is more acidic than phenol. In 4-nitrophenol nitro group has strong electron withdrawing resonance (-R) effect as well as electron withdrawing inductive (-I) effect. Due to these two effects the polarity of O-H bond of phenolic -OH group increases.
Is 2 nitrophenol polar?
