Molecular Structure and Isomerism

Question 1

Regarding isomers and isomerism (true or false):

Isomers have similar structures but different numbers of atoms

Answer 1

False. Isomers have similar structures made up of the same number of atoms.

Question 2

Regarding isomers and isomerism (true or false):

Isomers have similar potency and side-effect profiles

Answer 2

False. The differences in the arrangement of the atoms between isomers often leads to significant variation in potency and side-effects.

Question 3

Regarding isomers and isomerism (true or false):

Many anaesthetic drugs display isomerism

Answer 3

True

Question 4

Regarding isomers and isomerism (true or false):

Laevobupivacaine is stereoisomer developed from an existing drug

Answer 4

True. Levobupivacaine is the (S) enantiomer of bupivacaine, with a longer duration of action and lower toxicity.

Question 5

Regarding isomers and isomerism (true or false):

Cis-trans isomers are a type of diastereoismer

Answer 5

True
