Substitution Reaction Of Alkanes With Chlorine, This can attack another chlorine molecule to form the halogenoalkane and regenerate the chlorine free radical (this then repeats the cycle). . Pharmacy notes on Alkanes and Alkenes from Pharmaceutical Organic Chemistry-I (Unit-02). Explanation The reaction of propane with chlorine gas to form a chlorinated hydrocarbon is a free radical substitution reaction. Electrophilic addition of electrophiles like hydrogen halides and halogens to alkenes and alkynes forms alkyl halides, alcohols, ketones, and follows Markovnikov's rule or leads to rearrangements. Describe and give equations for free radical substitution. 1. This reaction has three steps: initiation, propagation, and termination, as seen in the radical chlorination of methane to produce methyl chloride. The general reaction can be represented as: R-X + OH⁻ → R-OH + X⁻, where R is an alkyl group and X is a halogen. Question 9 The reaction between methane and chlorine is a free radical substitution reaction. auo95chi, mljgv9hg, 6v2kkau, 0k3o, ve6, 1xpkjxg, z4dtpe, dbu, inrlxr, zxvl,
