When the conjugate acid of aniline, C6H5NH3+, reacts with the acetate ion, the following reaction takes place: C6H5NH3+(aq)+CH3COO(aq)C6H5NH2(aq)+CH3COOH(aq) If Kafor C6H5NH3+ is 1.35105 and Kafor CH3COOH is 1.86105 , what is K for the reaction?
Phenol and other derivatives with a single hydroxyl group on the aromatic ring are not easily oxidized to form a ketone. Why is this? Select all that apply: O Phenol is a secondary alcohol; secondary alcohols do not oxidize. O The carbon that the hydroxyl group is attached to in phenol does not have a hydrogen attached. Forming a double bond between the oxygen and the carbon would require breaking up the stable aromatic ring. Phenol is a tertiary alcohol, which does not oxidize.
