Question 1

Enantiomers

Answer 1

They are connected the same way but their spatial arrangement of the atoms of the chiral carbon is different

Question 2

diastereomers

Answer 2

When some (but not all) of the chiral centres have changed (not the same)
RRR->SRS

Question 3

Mesocompounds

Answer 3

These are optically inactive molecules as they cannot rotate a plane of light. These compounds have an internal plane of symmetry that divides the compound in half, which are mirror images of each other.
-As a result, even though they may have chiral centres, the presence of an internal plane of symmetry leads to a cancelation of the optical activity making compounds optically inactive

Question 4

Why are mesocompounds important

Answer 4

They provide an exception to the rule of all chiral molecules are optically active and so understanding them is crucial for accurately predicting and interpreting the systems of chemistry

Question 5

Properties of mesocompounds

Answer 5

-Have chiral centres
-have internal plane of symmetry
-Are optically inactive
