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.

For the molecular formula C5H10, the cyclic structural isomers include cyclopentane, 1-methylcyclobutane, and 2-methylcyclobutane. Additionally, 1,2-dimethylcyclobutane can also be considered. In terms of stereoisomers for these cyclic structures, only 1,2-dimethylcyclobutane has stereoisomers due to the presence of chiral centers, while the others do not.
Nonane has a total of 75 isomers, which includes straight chain isomers, branched chain isomers, and cyclic isomers.
hydrocarbons, they are called isomers
There are two isomers for dibromopropane: 1,2-dibromopropane and 2,2-dibromopropane.

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.
Nonane has a total of 75 isomers, which includes straight chain isomers, branched chain isomers, and cyclic isomers.
Tartaric acid has three stereoisomers: meso-tartaric acid and the two enantiomers, D-tartaric acid and L-tartaric acid.

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.
A carbon atom attached to four different groups through sigma bonds is an asymmetric carbon or chiral carbon, this phenomenon is CHIRALITY, it is a basic centre for existing of Enantiomers the stereo isomers.
Three types of isomers are structural isomers (different connectivity of atoms), stereoisomers (same connectivity but different spatial arrangement), and conformational isomers (different spatial arrangement due to rotation around single bonds).

E isomers are entgegen isomers. The groups with the highest priority are located on opposite sides of a double bond.
