The relationship between the pair of compounds shown below is respectively:

The separation of a racemic mixture into pure enantiomers is termed as

Which of the following is expected to be optically active?

In the reaction sequence shown below,determine the total number of stereoisomers formed as the final product $D$. The starting material is $CH_3-CD(CH_3)-C \equiv C-CO-CH_3$. The reaction $A$ is $LiAlH_4$ (or similar reducing agent to reduce the alkyne to a cis-alkene),$C$ is the cis-isomer,and the final step is the addition of $Br_2/CCl_4$.

The isomers whose structures are non-superimposable mirror images of each other are called .....

Which of the following cyclopentane derivatives is optically inactive?
