ANSWER PART 1. (UPLOADED PICTURE)
ANSWER PART 2. (UPLOADED PICTURE)
ANSWER PART 3: PKa value is used to determine the strength of an acid. The lower the PKa value, the stronger the acid.
Alcohol has a PKa value of 15(approximate)
2-Azetidinone ( functional group in Ezetimibe) has a PKa value of 11.3 (approximate)
2-Aminoimidazole ( functional group in Clonidine) has a PKa value of 8.5(approximate)
ANSWER PART
4: The 2-Aminoimidazole (functional group in
Clonidine) is the most basic of all because of presence of 3
Nitrogen groups. It is a derivative of a strong base guanidine
.
