Concept explainers
(a)
Interpretation:
The optically inactive compound for the given molecular formula has to be drawn.
Concept introduction:
Optical activity of a molecule is the interaction between molecule and plane-polarized light.
Molecule having asymmetric center shows optical activity except mesocompounds.
Asymmetric center is a stereocenter which arises to hydrocarbons if the carbon is bonded to four different groups.
Mesocompounds has asymmetric centers and a plane of symmetry, so the molecule superimposable on its mirror image, thereby the compound is achiral.
If the four groups attached to both asymmetric centers of a compound are identical, then the compound is a mesocompound.
(b)
Interpretation:
The mesocompound (optically inactive compound) for the given molecular formula has to be drawn.
Concept introduction:
Optical activity of a molecule is the interaction between molecule and plane-polarized light.
Molecule having asymmetric center shows optical activity except mesocompounds.
Asymmetric center is a stereocenter which arises to hydrocarbons if the carbon is bonded to four different groups.
Mesocompounds has asymmetric centers and a plane of symmetry, so the molecule superimposable on its mirror image, thereby the compound is achiral.
If the four groups attached to both asymmetric centers of a compound are identical, then the compound is a mesocompound.
Asymmetric center is arises to hydrocarbons if the carbon is bonded to four different groups.
(c)
Interpretation:
The optically active compound for the given molecular formula has to be drawn.
Concept introduction:
Optical activity of a molecule is the interaction between molecule and plane-polarized light.
Molecule having asymmetric center shows optical activity except mesocompounds.
Asymmetric center is a stereocenter which arises to hydrocarbons if the carbon is bonded to four different groups.
Mesocompounds has asymmetric centers and a plane of symmetry, so the molecule superimposable on its mirror image, thereby the compound is achiral.
If the four groups attached to both asymmetric centers of a compound is identical, then the compound is a mesocompound.
If a cyclic compound has two asymmetric centers with identical substituents, then cis-isomer of the compound is a mesocompound.
Asymmetric center is arises to hydrocarbons if the carbon is bonded to four different groups.
