1,2-Dichloroethane is a colorless, oily liquid that has a sweet taste, a chloroformlike odor, and a vola- tility similar to gasoline. It boils at 83.47°C, melts at -35.36°C, and has a density of 1.2351 at 20°C.
How do you make dichloroethane?
Production is primarily achieved through the iron(III) chloride-catalysed reaction of ethylene and chlorine: H2C=CH2 (g) + Cl2 (g) → ClCH2–CH2Cl (l) (ΔHr = −218 kJ/mol) 1,2-dichloroethane is also generated by the copper(II) chloride-catalysed oxychlorination of ethylene: 2 H2C=CH2 + 4 HCl + O2 → 2 ClCH2−CH2Cl + 2 H2O.

What is the shape of dichloroethane?
Planar 1,1-Dichloroethene, commonly called 1,1-dichloroethylene or vinylidene chloride or 1,1-DCE, is an organochloride with the molecular formula C2H2Cl2. … 1,1-Dichloroethene.
What is a shielding in NMR?
NMR spectroscopy is an ideal technique for identifying the structure of molecules using NMR spectroscopy. Higher electron density around hydrogen atoms creates greater opposition to the applied magnetic field. … These H atoms are referred to as being shielded.
How many NMR signals are there in methoxy ethane?
13C NMR SPECTRA (above): The 13C NMR spectra of propan-1-ol and methoxyethane show three different 13C NMR chemical shifts, but propan-2-ol can be distinguished from the other two by exhibiting only two chemical shift lines.
Does 1/2-dichloroethane have a dipole?
For example, in 1,2-dichloroethene, each unsaturated carbon atom has a chlorine atom and a hydrogen atom attached to it. … The two C—Cl bond moments of the trans isomer cancel each other, and the compound has no dipole moment. The cis isomer has a dipole moment because the two C—Cl bond moments reinforce each other.
What is dichloroethane used for?
The most common use of 1,2-dichloroethane is in the production of vinyl chloride which is used to make a variety of plastic and vinyl products including polyvinyl chloride (PVC) pipes, furniture and automobile upholstery, wall coverings, housewares, and automobile parts.
What is the point group of 1/2-dichloroethane?
1,2-dichloroethane is a member of the class of chloroethanes substituted by two chloro groups at positions 1 and 2. It has a role as a non-polar solvent, a hepatotoxic agent and a mutagen.
Which geometrical isomer of 1/2 dichloroethane have more melting and boiling point?
The boiling point of cis-1,2-dichloroethene is higher than corresponding trans-isomer.
Which has zero dipole moment 1 1 dichloroethene?
1 Dichloro ethylene is shown below. From the given structures it is clear that Trans-1,2—dichloroethylene and 1.1 Dichloroethylene has no dipole moment, as the bond dipoles of each structure get nullified with each other.
What does cis mean in chemistry?
this side of The prefixes cis and trans are from Latin: this side of and the other side of, respectively. In the context of chemistry, cis indicates that the functional groups (substituents) are on the same side of some plane, while trans conveys that they are on opposing sides.

What is Stereoisomerism which type of Stereoisomerism is shown by 1 2-dichloroethene draw the structures of its two isomers and name them?
The stereoisomerism is when isomerism is caused by the different arrangements of atoms or groups in space,the phenomenon is called stereoisomerism. The stereoisomers have the same structural formulas but differ in the arrangement of atoms in space. Geometrical Isomerism is shown by 1-2 dichloro Ethane.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
