plane polarised light is being used. A solution of one enantiomer rotates the plane of polarisation in a clockwise direction. This enantiomer is known as the (+) form. A solution of the other enantiomer rotates the plane of polarisation in an anti-clockwise direction. This enantiomer is known as the (-) form. If the solutions are equally concentrated the amount of rotation caused by the two isomers is exactly the same - but in opposite directions. When optically active substances are made in the lab, they often occur as a 50/50 mixture of the two enantiomers. This is known as a racemic mixture or racemate. It has no effect on plane polarised light.

Isomers are compounds that have?
Isomers have the same chemical formulas, but different structures. They can be drastically different in structure, such as constitutional isomers, which differ in the way that certain groups are linked to a carbon back bone. They can be very subtly different as well, such as stereo isomers, which are almost completely same except for their biological activities and interactions with plane polarized light.
Why are CH3CH2COOH and CH3CHOHCHO optical isomers?
These are not optical isomers they are functional group isomers a subcategory of structural isomers.
What are structural isomers?
i think it is when a molecule can be expressed in several different ways for example: C4H8 could be butane or 2 methyl propane. It would still have the same number of Carbons and Hydrogens but its structure would be different.
Three types of isomers?
The three main types of isomers are structural isomers, geometric isomers, and enantiomers.
Does RNA have isomers?
Yes, RNA does have isomers.
What are the isomers of C5H11Cl?
