intro to organic chemistry

Question 1

define structural isomerism

Answer 1

molecules with the some molecular formula but different structural formula

Question 2

define positional isomerism

Answer 2

molecules with the same functional group but functional group is attached to main chain at different places

Question 3

define functional group isomerism

Answer 3

same molecular formula but different functional group

Question 4

define chain isomerism

Answer 4

same molecular formula but hydrocarbon chain organised differently e.g. 4c chain v 2c chain

Question 5

how is E-Z isomerism caused and how is each isomer decided

Answer 5

E-Z isomerism is caused by limited rotation around a C=C double bond, groups with the highest atomic number on the same side is the Z isomer, if they are on different side it is the E isomer
