Stereochemistry

Question 1

what is chiral

Answer 1

an object that can’t be superimposed on it’s mirror image

Question 2

what is a chiral atom

Answer 2

an atom bonded to 4 different groups

Question 3

what is an enantiomer

Answer 3

opposite of disastiomer

Question 4

what is an isomer

Answer 4

same atoms in a molecule

Question 5

what is a stereoisomer

Answer 5

same atoms are all connected in 3D

Question 6

what is an achiral object

Answer 6

object that is superimposable on it’s mirror image

Question 7

what is the aufbau diagram and what does it mean

Answer 7

extra electrons may not necessarily fill the shells in a linear format

e.g.
1s
2s 2p
3s 3p 3d
4s

–> draw the lines diagonally and see that 3p –> 4s –> 3d

Question 8

what happens when when there is a large jump in ionization energy

Answer 8

it means the valence electrons have been removed e.g. energy required in the inner shell is > energy required to remove valence electrons

Question 9

what is an enantiomer and what is one of the requirements (not guarantees) that it will exist

Answer 9

an enantiomer is arrangement of molecules that is superimposable on it’s mirror image

if there is an enantiomer then there will be a chiral carbon
