5.1: introduction/overview of Isomerism

Question 1

what is an isomer

Answer 1

different compounds with the same formula

Question 2

what is stereochemsitry

Answer 2

the study of 3d structure of molecules and 3d aspects of reaction

Question 3

what is a constitutinal isomer

Answer 3

same formula, different connectivities

Question 4

what is a stereoisomer

Answer 4

same formula, same connectivity, different shape

Question 5

what is a stereocenter

Answer 5

an atom at which the interchange of two groups produces a stereoisomer

Question 6

what is a chirality center

Answer 6

a type of stereocenter where an atom is attached to four different groups

Question 7

what is an enantiomer

Answer 7

type of stereoisomer: pair of compounds that are nonsuperimposable mirror images, they can have chirality in more than one place or be locked

Question 8

what is a diaastereoisomer

Answer 8

not enantiolers meaning that their mirror images are not the same

Question 9

what are the type of diastereomers

Answer 9

cis trans isomers, distereomers, meso compounds

Question 10

what is a cis trans isomer

Answer 10

they differe in the geometric arrangmenet they have stereocenters that are NOT chirality centers

Question 11

what is a meso compound

Answer 11

more than one chirality center but are achiral or superimposable images
