Which of the following statement is FALSE about stereoisomerism?
Same molecular formula
Same structural formula
Different structural arrangement or connectivity
Different spatial arrangement
What is the relationship between 1 and 2?
diastereoisomers
enantiomers
no relationship
meso compounds
Can enantiomer rotates plane-polarised light?
Yes in all situations
No because it is optically active
Yes but it can only rotate the polarised light in opposite direction
No due to its restricted rotation of carbon-carbon double bond

Yes
False
