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.

∙ 14y agoOptical activity is the ability of a substance to rotate the plane of polarization of a beam of light passed through it, either as crystals or in solution.
Clockwise rotation as one faces the light source is "positive," or dextrorotary; counterclockwise rotation "negative," or levorotary.
Louis Pasteur was the first to recognize that molecules with optical activity are stereoisomers .

Methanol exhibiting optical activity?
No
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.
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 difference between concentration and activity?
Activity and Concentration • Activity - "effective concentration" • Ion-ion and ion-H2O interactions (hydration shell) cause number of ions available to react chemically ("free" ions) to be less than the number present • Concentration can be related to activity using the activity coefficient γ, where [a] = γ (c) we assume that activity, a, is equal to concentration, c, by setting γ = 1 when dealing with dilute aqueous solutions. But ions don't behave ideally . . . • Concentration related to activity using the activity coefficient γ, where [a] = γ (c) • The value of γ depends on: - Concentration of ions and charge in the solution - Charge of the ion - Diameter of the ion Activity coefficient γz → 1 as concentrations → 0

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.
