What is the definition of a chiral compound?
A chiral molecule is a molecule that is not superimposable on its mirror image
Which of the following statements is incorrect?
(+) in front of a chiral compound means that its specific rotation [α]D is positive
When [α]D > 0°, the plane-polarized light is rotated clockwise ⇒ the solution is said to be dextrorotary
How many chiral centers does the 2,4-dibromo-1,1,4-trimethylcyclohexane have?
Chiral center: atom connected to 4 different substituents
They are sometimes marked with an asterick
Which of the following compound is chiral?
2-bromobutane has 1 stereocenter ⇒ this molecule is chiral
The other molecules do not have a stereocenter ⇒ they are achiral
Which of the following compound is meso?
cis-1,3-dimethylcyclohexane is a meso compound
A meso compound is a compound that contains stereocenters but is achiral. It has a plane of symmetry
What is the enantiomer of the (1S,3S)-1-bromo-3-methylcyclohexane?
2 enantiomers have opposite configurations in all chirality centers
