Optical isomers are those which have one or more asymmetric carbon atoms their optical activity means a tendency to rotate the plane of plane polarized light but some of such molecules have an internal symmetry as meso form of Tartaric acid , this is the optical isomer of Tartaric acid but is optically inactive.

What is the difference between active flood plain and old flood plain?
Active floodplains are areas that are regularly inundated by floodwaters and play a role in the natural flow of water. Old floodplains are former floodplain areas that have been abandoned due to changes in water channels or human interventions. Active floodplains are still actively involved in the flood process, while old floodplains may have shifted away from being actively inundated.
What is something similar between active and passive margins continents?
Both active and passive margins are found at the edges of continents. Active margins are associated with tectonic activity and are typically marked by earthquakes, volcanoes, and mountain building, while passive margins are geologically stable and characterized by broad continental shelves and sediment deposition.
What does the passive continental margin have that the active margin does not?
Subduction. A subduction trench.
What is the difference between active and passive remote sensing systems in geography?
Active remote sensing transmits energy to allow an image to be formed. Passive remote sensing collects energy reflected or emitted from a surface. Active systems direct a bean of energy at a surface and analyze the energy reflected back. An example of active sensing would be a radar. Passive systems are pretty much what the eyes see, and it's like a photograph. Passive sensing radiates visible light.
What exists between the two poles of a magnet?
A magnetic field exists between the two poles of a magnet. This field is the region where magnetic forces are active and can influence other magnetic materials or objects within its proximity.
What are optical active substances?
Optically active substances are those substances that rotate the plane of polarized light to the left or right.
What is difference between a racemic mixture and a meso compound?
Both are optically inactive, but for different reasons. A racemic mixture contains chiral molecules that, individually, are optically active. But the mixture contains optically active enantiomers, which essentially cancel out each other's optical activity (one enantiomer rotates light one way, the other rotates it back). A meso compound, however, is optically inactive on its own. It can have chiral centers within its structure, but due to symmetry it will still be optically inactive.
What are optical substances?
Optically active substances are those substances that rotate the plane of polarized light to the left or right.
Why meso compounds are optically active?
Meso compounds contain an internal plane of symmetry, which results in equal and opposite optical rotations cancelling each other out, giving the appearance of optically inactive behavior. However, if the meso compound is resolved into its enantiomeric forms, each enantiomer will exhibit optical activity. Thus, meso compounds are considered optically active at the level of their enantiomers.
Are diastereomers optically active?
Diastereomers have different physical and chemical properties, and therefore can have different optical activities. Some diastereomers may be optically active, while others may not be. It depends on their specific molecular structures and whether they contain chiral centers.
Is allene optically active or not?
Yes, allene is optically active due to its chirality. It has two chiral centers, resulting in four stereoisomers, two of which are enantiomers that are optically active.
Is water optically active?
Water is not optically active. It does not rotate the plane of polarized light, which is a characteristic typically associated with optically active substances.
Which compound without chirality gives optical activity?
touluene All Biphenyls and Allenes are optically active without a chiral center
Is phenylmethanol optically active?
No, phenylmethanol is not optically active because it lacks a chiral center. It does not have a stereocenter that would give rise to enantiomers.
What is asymmetrical symmetry?
The synthesis of an optically active compound from an optically inactive compound with or without using an optically active reagent.
Difference between active and passive optical component?
Fiber optic couplers can be either active or passive devices. The difference between active and passive couplers is that a passive coupler redistributes the optical signal without optical-to-electrical conversion. Active couplers are electronic devices that split or combine the signal electrically and use fiber optic detectors and sources for input and output.
What does optically active mean in organic chemistry?
Optically active compounds have the ability to rotate plane-polarized light. This property arises from the presence of a chiral center in the molecule, leading to two non-superimposable mirror-image forms (enantiomers). These enantiomers interact with plane-polarized light in opposite ways, leading to optical activity.
