(a)

Interpretation Introduction

Interpretation:

The position of lactone group that forms the ring is to be stated.

Concept introduction:

In the family of macrolide antibiotics, they all have large ring (macrocycle) and an ester is present that makes the ring. A cyclic ester is known as lactone.

In the mid-1930s a substance was isolated from a fungus that is a parasite of ryes and other grasses. This alkaloid, lysergic acid, has been of great interest to chemists because of its strange, dramatic action on the human mind. Many derivatives of lysergic acid are known, some with medicinal applications. Perhaps the best known derivative of lysergic acid is the potent hallucinogen lysergic acid diethylamide (LSD): మగవా జి N-H LSD (CH25N;O) Like other alkaloids, LSD is a weak base, with Kp = 7.6 × 107. What is the pH of a 0.94 M solution of LSD? pH =

Aspirin is the common name for the compound acetylsalicylic acid, widely used as a fever reducer and as a pain killer. Salicylic acid, whose name comes from Salix, the willow family of plants, was derived from willow bark extracts. In folk medicine, willow bark teas were used as headache remedies and other tonics. Nowadays, salicylic acid is administered in the form of aspirin which is less irritating to the stomach than salicylic acid. To prepare aspirin, salicylic acid is reacted with an excess of acetic anhydride. A small amount of a strong acid is used as a catalyst which speeds up the reaction. In this experiment, phosphoric acid will be used as the catalyst. The excess acetic acid will be quenched with the addition of water. The aspirin product is not very soluble in water so the aspirin product will precipitate when water is added. The synthesis reaction of aspirin is shown below: Actic anhydride 5 ml. Acetic acid Salicylic acid 28 Acetylsalicylie acid Procedure 1) Mix salicylic…
