Select the true statement
Phenol reacts with sodium hydroxide but not sodium carbonate
Phenol reacts with sodium carbonate but not with sodium hydroxide
Phenol reacts with neither sodium carbonate nor sodium carbonate
Phenol reacts with both sodium hydroxide and sodium carbonate
Select the true statement
Phenol reacts with both sodium hydroxide and sodium carbonate but carboxylic acids react with neither
Both phenols and carboxylic acids react with sodium carbonate
Carboxylic acids react with sodium hydroxide and sodium carbonate but phenols react with neither

Select the true statement
Phenol is less reactive than benzene because the-OH group donates electron density to the aromatic ring
Phenol is less reactive than benzene because the -OH group removes electron density from the aromatic ring
Phenol is more reactive than benzene because the -OH group removes electron density to the aromatic ring
Phenol is more reactive than benzene because the -OH group donates electron density to the aromatic ring
Select the true statement
