DF 10 - Isomerism Flashcards
1
Q
What are structural isomers?
A
Structural isomers are hydrocarbons with the same molecular formula, but different structural formulae
2
Q
What are stereoisomers?
A
Stereoisomers are hydrocarbons with the same structural formula, but different arrangements of their atoms in 3D
3
Q
Why does stereoisomerism occur around a double bond?
A
Free rotation is restricted around the double bond. When each carbon has two different groups attached to it different arrangements are possible about the C=C
4
Q
What is cis-trans isomerism?
A
Cis-trans isomerism is a type of E-Z isomerism that occurs when each carbon in the double bond has one group in common
