Test: Chirality - Chemistry MCQ

In order for a molecule to be chiral, it must not be superimposable on its mirror image. Molecules with a plane of symmetry or a center of symmetry do not meet this criterion. Molecule I ,II and III are not having plane of symmetry, they are chiral molecule..

In order for a molecule to be achiral, it must be superimposable on its mirror image. Molecules with a center of symmetry and/or plane of symmetry meet this criterion.
The given molecule has centre of symmetry for the given figure.
For the given compound has rotation about C-C single bond is also possible, so after rotating one C while another is kept stationary, we get the structure where plane of symmetry passing through middle of the bond to get mirror images.
The plane of symmetry of the molecule is show below:

In order for a molecule to be chiral, it must not be superimposable on its mirror image. Molecules with a plane of symmetry or a center of symmetry do not meet this criterion. Molecule A has a plane of symmetry (shown above in fuchsia), molecule B has no symmetry.

In order for a molecule to be achiral, it must be superimposable on its mirror image. Molecules with a plane of symmetry or a center of symmetry meet this criterion.

Chirality is not restricted to molecules. While it is common for the presence of a carbon atom in a molecule with four different substituents to be the origin of chirality of a compound, it is not a requirement for chirality.

In order for a molecule to be chiral, it must not be superimposable on its mirror image. Molecules with a plane of symmetry or a center of symmetry do not meet this criterion. Molecule II and III are not having symmetry element, they are chiral molecule. Molecule ‘I’ is having plane of symmetry, it is an achiral atom.

In order for a molecule to be chiral, it must not be superimposable on its mirror image. Molecules with a plane of symmetry or a center of symmetry do not meet this criterion. This molecule is not having any symmetry element, it is a chiral molecule.

In order for a molecule to be chiral, it must not be superimposable on its mirror image. Molecules with a plane of symmetry or a center of symmetry do not meet this criterion. This molecule is having plane of symmetry, it is an achiral molecule.

Chiral molecules are non-superimposable on their mirror images. A good way to determine whether a molecule is chiral is to determine whether it has a plane of symmetry. A molecule with a plane of symmetry is achiral (not chiral). Molecule 1 does not have a plane of symmetry so it is chiral. Molecules 2 and 3 both have planes of symmetry, so they are not chiral.

Follow the direction of the remaining 3 priorities from highest to lowest priority (lowest to highest number, 1<2<3). A clockwise direction is an R (rectus, Latin for right) configuration. A dextrorotary compound is often prefixed “(+)-” or “d-“
