Question 18

structural isomers

Answer 18

have the same molecular formula but a different structural formula.
3 types-chain, position, functional group

Question 19

position isomer

Answer 19

have the same molecular formula but a different position of the functional group on the carbon skeleton

Question 19

chain isomer

Answer 19

have the same molecular formula but a different arrangement of the carbon skeleton

Question 20

functional group isomer

Answer 20

have the same molecular formula but a different functional group

Question 21

stereoisomers

Answer 21

compounds with the same structural formulas with atoms arranged differently in space

Question 22

what is E/Z isomerism?

Answer 22

is a form of stereoisomerism and occurs as a result of restricted rotation about the planar carbon to carbon double bond
E-opposite
Z- together

Question 23

when are CIP priority rules used?

Answer 23

when deciding if an isomer is E/Z when we have 4 different groups around the double bond
