What is the cause of optical activity?
Optical activity happens in a solution with components of quartz, sugar or certain gases. It is when the plane of linearly polarized light is turns to the direction of movement through the components.
What is the necessary condition for a molecule to exibit optical activity?
The molecule must have chirality - an assymetry in which the molecule can't be turned around to look like its mirror image.
Optical isomers of tartaric acid?
Tartaric acid though it contains four chiral carbons will exists in three isomeric forms i.e., (+), (-), and meso.(+) and (-) tartaric acids are mirror images of each other and are hence enantiomers while meso is not a mirror image of either of them.
What are the precautions to be taken while using UV spectrophotometer?
One should not touch the optical assembly with bear hands. Optical surface of cuvettes should not be touched with fingers to avoid erratic reading. Always ensure effectiveness of silica gel kept in instrument. Preserve the instrument from dust particles. Never wash the cuvettes with chromic acid. Wash the cuvette with the distilled water and then with methanol before storage. Check the calibration status before using the instrument and ensure the timely calibration. Do not overfill the cuvettes. Perform the visual inspection of cuvettes for suitability.
Why are CH3CH2COOH and CH3CHOHCHO optical isomers?
These are not optical isomers they are functional group isomers a subcategory of structural isomers.
What is the cause of optical activity?

optical lobe of the cortex
Why do some isomers lack optical activity?
doesnt have the right number of neutrons
What areThe uses of a polarimeter?
The instrument is used to measure the optical activity of a sample.
What type of crystals exhibit optical activity?
whoever knows please answer below :P
Why is it important for the solution to be clear before you attempt to measure its optical activity?
'cause, yo
What has the author Azucena Santiago Denes written?
Azucena Santiago Denes has written: 'Studies on the one-electron theory of optical activity' -- subject(s): Molecular orbitals, Optical rotation, Dichroism
What is the difference between optical isomer and optically active isomer?
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 has the author Laurence A Nafie written?
Laurence A. Nafie has written: 'Vibrational optical activity' -- subject(s): Vibrational spectra
How much water does an average rainbow hold?
What a charming question! But since the rainbow has no physical presence, it contains nothing. It is just an optical effect. Another optical effect could be that of a shadow, which really has no presence or activity.
Which compound without chirality gives optical activity?
touluene All Biphenyls and Allenes are optically active without a chiral center
