What is stilbene dibromide used for?
Stilbene is used in manufacture of dyes and optical brighteners, and also as a phosphor and a scintillator. Stilbene is one of the gain mediums used in dye lasers.
Is optically inactive?
A compound incapable of optical rotation is said to be optically inactive. All pure achiral compounds are optically inactive. eg: Chloroethane (1) is achiral and does not rotate the plane of plane-polarized light. Thus, 1 is optically inactive.
Can you rotate a meso compound?
Just to make things clear, a meso compound is a molecule that has chiral centers but also has an internal plane of symmetry. This renders the molecule achiral: it does not have an enantiomer, and it does not rotate plane polarized light .
Why did you use pyridinium bromide Perbromide instead of bromine?
In these two bromination reactions, pyridinium tribromide will be used as the source of bromine. This solid reagent is safer and easier to handle than elemental bromine, which is a highly corrosive liquid.
Is pyridinium tribromide carcinogenic?
Carcinogenicity: CAS# 39416-48-3: Not listed by ACGIH, IARC, NTP, or CA Prop 65. Epidemiology: No information available. Reproductive Effects: No information available.
Is stilbene a Lachrymator?
Stilbene dibromide is corrosive and a lachrymator. It may cause irritation to skin, the digestive tract (if swallowed), and respiratory tract (if inhaled).

How are the melting points of racemic and meso isomer different?
Like all diastereomers, the racemic mixture and the meso isomer have different physical properties. Most notable is that the melting points differ markedly, with the racemic mixture melting at 114° and the meso compound melting in the range 241-243°.
How are cis and trans isomers of stilbene different?
Since the cis and trans isomers of stilbene have different geometries, it follows that upon reaction with bromine they give rise to stereoisomeric bromonium ions and, eventually, products that differ only by their stereochemistry. The product of this reaction, 1,2-dibromo-1,2-diphenylethane, has two stereogenic
