Which of the following is a chiral molecule? (Hint: Draw the molecules.)

Which of the following correctly defines an achiral object?

Is 1,4-dimethylcyclohexane a chiral molecule? If yes, identify its chiral centers:

Why is 3-aminopentane achiral while 3-aminohexane is chiral?

Determine whether any chiral centers are present in the compound below. Label the chiral centers with an asterisk (*), if applicable:

Use an asterisk (*) to mark the chiral centers, if any, in 1,1-dihydroxybutan-2-one, commonly used as a plant growth regulator.
