(a)
Interpretation:
Configuration for the chirality center should be identified.
Concept introduction:
Chiral: Four different atoms attached to a carbon atom is called chiral molecule.
Stereoisomers: Stereoisomers are molecules that have the same molecular formula and they differ only in arrangement of atom in three-dimensional space.
Cahn–Ingold–Prelog system: The first priority goes to the atom in a molecule whose
Draw a curve from the first-priority substituent through the second-priority substituent and then through the third.
If the curve goes clockwise, the chiral center is designated R; if the curve goes counterclockwise, the chiral center is designated S.
To find: Configuration for the chirality center

Stereoisomers: Stereoisomers are molecules that have the same molecular formula and they differ only in arrangement of atom in three-dimensional space.
Cahn–Ingold–Prelog system: The first priority goes to the atom in a molecule whose atomic number is higher. After assigning the priorities to each of the substituents, rotate the molecule so that the number-four priority substituent is oriented in the back.
Draw a curve from the first-priority substituent through the second-priority substituent and then through the third.
