The two enantiomers of 2,4-dibromopentane are the two isomers in which the absolute stereodescriptors of the two stereogenic centers are both R or both S. The two compounds are named as (R,R)-2,4-dibromopentane and (S,S)-2,4-dibromopentane.
(R,S)-2,4-dibromopentane, which contains a mirror plane defined by the central atom and the two hydrogen atoms attached to it, is the meso form.

How many stereo isomers of 2 3-butanediol are possibles?
There are two possible stereoisomers of 2,3-butanediol: meso and chiral forms. The meso form has an internal plane of symmetry, resulting in only one unique 3D structure. The chiral form, on the other hand, has two enantiomeric forms (mirror images) due to the presence of a chiral center at the carbon atoms.
The reaction of cis-2-butene with basic permanganate gives a product which is optically inactive even though it possess to chiral centresWhy?
The product is optically inactive because the reaction results in a meso compound, which has an internal plane of symmetry that makes it superimposable on its mirror image. This cancels out any optical activity in the molecule, even though it has two chiral centers.
What is the equation clearly showing the stereochemistry of the starting material and the product for the reaction of 2-bromobutane with sodium iodide in acetone?
2-bromobutane undergoes an SN2 reaction with sodium iodide in acetone, resulting in the substitution of the bromine atom with an iodine atom. The stereochemistry of the product is inversion of configuration, meaning the product is the opposite enantiomer of the starting material. The equation for this reaction can be represented as: (R)-2-bromobutane + NaI → (S)-2-iodobutane + NaBr

What is the formation of oxygen ions?
Oxygen ions typically form in one of two ways: either by gaining two electrons to form O^2- ions, or by losing two electrons to form O^2+ ions. The most common form of oxygen ion is the oxide ion (O^2-).

It was located in the basins of the Tigris and Euphrates Rivers. Meso = between, potamos = rever in Greek.
