(i)

(j)

Step-by-step solution

Reaction of Compound a,b,c

Compound a reaction:

The reaction of the acyl chloride with the potassium fluoride leads to the formation of the acyl fluoride by the removal of potassium chloride as shown below:

Compound b reaction:

The reaction of the cyclopentanone on reaction with the water in presence of water leads to the ring opening by breaking the bond. On the addition of the hydroxyl group of the water to the carbonyl carbon and forming the carboxylic acid named pentanoic acid.

Compound c reaction:

When carboxylic acid reacts with thionyl chloride production of acyl chloride occurs by replacinga hydroxyl group from chloride ion further on reaction with amine amide formation occur as shown below:

Reaction of Compound d,e,f

Compound d reaction:

The reaction of acetic anhydride in presence of water form the di-substituted acid by the attack of water molecule the hydroxyl addition takes place to the carbonyl carbon and the cyclic anhydride opens as di- substituted acid as shown below:

Compound e reaction:

The given reaction leads to the removal of two equivalent of the HCl so that the cyclic anhydride is formed on the benzene ring as shown:

Compound f reaction:

The reaction of cyclic acetic anhydride in presence of water form the di-substituted acid by the attack of water molecule the hydroxyl addition takes place to the carbonyl carbon and the cyclic anhydride open as di- substituted acid but when excess water is present one terminal acid leads to form the alcohol on reduction as shown below:

Reaction of Compound g,h,i,j

Compound g reaction:

The reaction of acetic anhydride with the excess alcohol formation of the carboxylic acid and ether occurred by breaking of carbonyl carbon and anhydride oxygen as shown below:

Compound h reaction:

The reaction of 1,2-benzoic acid with acetic anhydride leads to the loss of water from carboxylic acid leading to the cyclization from the oxygen of the carboxylic acid formation of cyclic anhydride occurs as shown below:

Compound i reaction:

The reactionof the given reactant with the excess ammonia leads to the breaking the cyclic anhydride ring and amine group attached to the carbonyl carbon as shown below:

Compound j reaction:

The reaction of the given reactant with the excess of alcohol leads to breaking the cyclic anhydride ring between the carbonyl carbon and the anhydride oxygen formation of ester as the attack of -OCH₃ alcohol occur by abstraction of proton that is an attack of and ester formed as shown below:
