What are vinyllic organohalides? How would you be able to identify them? Thanks
I think you mean vinyl organohalides.

Vinyl Chloride, H2C=CHCl would be the simplest compound in this group. Any one of the H's can be replaced by an alkyl group to form a more complicated vinyl organohalide. Vinyl molecules (monomers) can link together to form polyvinyl chloride plastics (PVC).
A simple test for for the monomer and possibly the polymer is to dip or coat a hot copper wire in the compound, then place it in a very hot flame. Traces of copper chloride form in the flame and color it green. This is called the Beilstein test for organic cholorides.
Vinyllic organohalides are a specific group of organic compounds that contain a halogen atom (such as chlorine, bromine, or iodine) bonded to a vinyl group (-CH=CH2). The vinyl group consists of a carbon-carbon double bond.
To identify vinyllic organohalides, you can follow these steps:
1. Look for a double bond: Vinyllic organohalides always have a carbon-carbon double bond in the molecule. This double bond is responsible for their characteristic reactivity and physical properties.
2. Identify the halogen atom: Look for the presence of halogen atoms, such as chlorine (Cl), bromine (Br), or iodine (I) bonded to the carbon atoms adjacent to the vinyl group. The halogen atom is usually bonded to one of the carbon atoms in the vinyl group.
3. Check for other substituents: Vinyllic organohalides may have additional substituents bonded to the carbon atoms adjacent to the vinyl group or on other parts of the molecule. These substituents can vary, but they are not directly connected to the halogen atom.
4. Analytical techniques: Various analytical techniques can help confirm the presence of vinyllic organohalides, such as nuclear magnetic resonance (NMR) spectroscopy, infrared (IR) spectroscopy, and mass spectrometry (MS). These techniques provide valuable information about the molecular structure, functional groups, and elemental composition.
5. Comparison with reference compounds: Compare your findings with known vinyllic organohalide compounds or reference spectra available in scientific databases or literature. By comparing the physical and spectroscopic properties, you can further confirm the identity of the compound.
Remember, it is crucial to follow appropriate safety measures when working with organic compounds, especially halogenated compounds, as they can be hazardous. Consult relevant safety guidelines and procedures before handling these chemicals.
