Chirality and optical activity are related concepts, but they are not synonymous. Chirality refers to the geometric property of a molecule having a non-superimposable mirror image, typically due to the presence of a chiral center. Optical activity, on the other hand, is the ability of chiral molecules to rotate the plane of polarized light. While all optically active substances are chiral, not all chiral substances exhibit optical activity under certain conditions, such as when they are present in racemic mixtures.

How does optical activity depend on state of substance?
Optical activity in a substance depends on its symmetry and chirality. Chiral molecules exhibit optical activity, where they rotate the plane of polarized light. The state of the substance, such as solid, liquid, or gas, does not significantly affect its optical activity as long as the molecular structure and chirality remain the same.
Which compound without chirality gives optical activity?
touluene All Biphenyls and Allenes are optically active without a chiral center
What is the necessary condition for a molecule to exibit optical activity?
The necessary condition for a molecule to exhibit optical activity is for it to be chiral, meaning it cannot have a plane of symmetry. This asymmetry causes the molecule to interact differently with polarized light, rotating the plane of polarization as it passes through.

Same
How can one identify chirality centers in a molecule?
Chirality centers in a molecule can be identified by looking for carbon atoms that are bonded to four different groups. These carbon atoms are asymmetric and give the molecule its chirality.
A fermion can have positive or negative chirality but what interactions determine or can change this?
Chirality of a fermion is determined by the interaction with the Higgs field. In the Standard Model, the Higgs mechanism is responsible for giving mass to fermions and changing their chirality. Flavor-changing interactions, such as weak interactions, can also potentially change the chirality of fermions.
What is the relationship between helicity and chirality in molecular structures?
Helicity and chirality are related concepts in molecular structures. Helicity refers to the direction of a spiral or twist in a molecule, while chirality refers to the asymmetry of a molecule that cannot be superimposed on its mirror image. In some cases, the helicity of a molecule can determine its chirality, but not always.
Why do some isomers lack optical activity?
Some isomers lack optical activity because they have a plane of symmetry or a center of symmetry that results in the molecule being superimposable on its mirror image. This makes them achiral and unable to rotate the plane of polarized light, thus lacking optical activity.
What is biochirality?
Biochirality is the chirality - of biological molecules, especially the study of the genesis of such chirality - the phenomenon by which two biological molecules are symmetrical.
How many chirality centers are there for psicose?
Psicose has four chiral carbon atoms, so it has four chirality centers.
Methanol exhibiting optical activity?
Methanol does not exhibit optical activity because it lacks a chiral center. Optical activity in organic compounds arises from the presence of a chiral carbon atom, which is asymmetric and lacks mirror symmetry. In methanol, the carbon atom bonded to the hydroxyl group is not chiral, leading to the compound being optically inactive.
What is the significance of chirality in the field of physics?
Chirality is important in physics because it affects how particles and molecules interact with each other. In particular, chirality can influence the behavior of light, the properties of materials, and the way certain chemical reactions occur. Understanding chirality is crucial for studying many natural phenomena and designing new technologies.
