Chloroethane is used as a starting material for the production of 'time-release capsules' in pharmaceutical products One way of preparing chloroethane is to react chlorine and ethane in the presence of ultraviolet light. Which statement is correct about the first stage of the mechanism of this reaction? B c D The Cl Cl bond is split homolytically_
Chloroethane (CE) gas carcinogenicity is analyzed and determined from a National Toxicology Program (NTP) bioassay where an inhalation concentration of 15,000 ppm CE gas in air produced the highest incidence of an uncommon-to-rare tumor ever observed by the NTP.

1,1-DCA to chloroethane (CA) analogous to reductive dechlo-rination of their chlorinated ethene counterparts trichloro-ethene (TCE), and cis-dichloroethene (cDCE), to vinyl chloride (VC) and finally to ethene. Bioremediation has become a cost-effective strategy for cleanup of sites con-taminated with chlorinated ethenes (5). For 1,1,1-TCA and
Give a curved-arrow mechanism for the following electrophilic substitution reaction. Solution Construct the mechanism in terms of the three preceding steps. Step 1 In this reaction, a hydrogen of the benzene ring has been replaced by an isotope D, which must come from the D 2SO 4. Because protons (in the form of Brønsted acids) are good ...
The product, ethane-1,2-diol, can be formed from mild oxidation of ethene. As such, it is possible to eliminate HCl from chloroethane to form ethene and subsequently, use cold KMnO4 to oxidise ethene to ethane-1,2-diol. The thinking process for this question involves the order of substitution.
10.10. A hydrocarbon C 5 H 10 does not react with chlorine in dark but gives a single monochloro compound C 5 H 9 Cl in bright sunlight. Identify the hydrocarbon. Ans. The hydrocarbon with molecular formula C 5 H 10 can either a cycloalkane or an alkene.Since the compound does not react with Cl 2 in the dark, therefore it cannot be an alkene but must be a cycloalkane.

Chloroethane is a colorless gas at room temperature and pressure. It has a characteristically sharp smell. It is a liquid when stored in pressurized containers; however, the liquid evaporates quickly when exposed to room air. Chloroethane catches fire easily.
2 Answers 2. Because hydrogen cyanide is not a very strong acid. Potassium cyanide exists as potassium and cyanide ions, so here the cyanide ions can act as strong nucleophiles. Hydrogen cyanide is only a weak acid and so it will not dissociate to produce a significant amount of the cyanide ion nucleophiles.
