Benzene is prepared from ethyne by the process of cyclic polymerization. In this process, Ethyne is passed through a red-hot iron tube at 873 K. The ethyne molecule then undergoes cyclic polymerization to form benzene.

How do you replace H with D?
Due to the acidic nature of α hydrogens they can be exchanged with deuterium by reaction with D2O (heavy water). The process is accelerated by the addition of an acid or base; an excess of D2O is required. The end result is the complete exchange of all α hydrogens with deuterium.
What does d2 mean in organic chemistry?
Hydrogen-d2. Deuterium molecule. Hydrogen, isotope of mass 2.

What is och3 in chemistry?
A methoxy group is the functional group consisting of a methyl group bound to oxygen. This alkoxy group has the formula O–CH3. On a benzene ring, the Hammett equation classifies a methoxy substituent at the para position as an electron-donating group, but as an electron-withdrawing group if at the meta position.
How do you put no2 on a ChemDoodle?

Is D heavier than H?
Because of the additional particle, deuterium is “heavier” than normal hydrogen. Water is composed of two hydrogen atoms and an oxygen atom. Heavy water, also called deuterium oxide, is composed of two deuterium atoms and an oxygen atom.
Why is deuterium used in organic chemistry?
Organic molecules that contain carbon–hydrogen bonds constantly undergo myriad reactions. Organic chemists use deuterium to investigate reaction mechanism.
What is HDO water?
Semiheavy water, HDO, exists whenever there is water with light hydrogen (protium, 1. H) and deuterium (D or 2. H) in the mix. This is because hydrogen atoms (hydrogen-1 and deuterium) are rapidly exchanged between water molecules.
What is EZ sequence rule?
E/Z System of Nomenclature of Geometrical Isomers. Cahn – Ingold – Prelog priority sequence can be usefully applied in giving names to such a structure. The group of highest priority, on both the double bonded carbon atom is first chosen. If the two group of highest priority are on the opposite side of the double bond.
What is EZ system?
The E/Z system analyzes the two substituents attached to each carbon in the double bond and assigns each either a high or low priority. If the higher priority group on both carbons in the double bond the same side the alkene is said to have a Z isomer (from German zusammen = together).
Which has higher priority E or Z?
(E)- : the higher priority groups are on opposite sides of the double bond. (Z)- : the higher priority groups are on the same side of the double bond.
