Answer:
D. Sulfonation
Explanation:
Electrophilic aromatic substitution -
The subsitution reaction , where the hydrogen atom of an aromatic ring is replaced by an external electrophile .
Sulfonation reaction -
The subsitution reaction , where the hydrogen atom of an aromatic ring ( benzene) is replaced by an sulfonyl group , is called an Sulfonation reaction .
The Sulfonation reaction is reversible in nature , because , heating of aqueous sulfuric acid with sulfonic acid , can lead to a reverse reaction , i.e. , desulfonation .
Answer:
always repeats the same unit
made of smaller molecules
often made from repeating units
Water is a liquid while hydrogen sulphide is a gas because the hydrogen bonding in water causes the water molecules to be associated with each other due to intermolecular forces of attraction.
According to Arrhenius Theory of acids and bases, an Arrhenius base produces OH-.
Among the four options, (3) LiOH is the correct one because it can separate into Li+ and OH- when being put in water.
Hope this helps~
