(a)
Interpretation:
The presence of asymmetric centers in the given compounds has to be checked.
Concept introduction:
Stereoisomers are isomers which have different spatial arrangement in spite of same bond connectivity. Stereoisomers are due to the presence of stereo center.
Asymmetric center is a stereo center which arises to hydrocarbons if the carbon is bonded to four different groups.
(b)
Interpretation:
The chirality of the given compounds has to be checked.
Concept introduction:
Optical activity (chirality) of a molecule is the interaction between molecule and plane-polarized light.
Molecule having asymmetric center shows optical activity except mesocompounds.
If a compound having non-superimposable mirror image, then the compound is chiral.
