The molecular formula C 6 H 7 NO (molar mass: 109.13 g/mol) may refer to: Aminophenols. 2-Aminophenol; 3-Aminophenol; 4-Aminophenol; Nicotinyl alcohol ...
Diethyl ether has higher water solubility of 8 g per 100 mL, versus diphenyl ether, with a solubility of 0.002 g per 100 mL. [ 3 ] [ 4 ] The presence of the aromatic ring also draws electrons away from the ethereal oxygen, making the hydrolysis of a phenol ether significantly more difficult than that of an alkyl ether.
