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) (ΔH_r = −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 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?
