Question

Complete the following as fully as possible. Do not leave any answers blank. Fully explain all answers. 1) Show a complete, detailed mechanism for the following reaction. Be sure to include all electron movement and all initiation, propagation and termination steps. CH3CH2 + Cl2 CH3CH2Cl + HCI

Answer 1

Initiation: propagafon: + CH CH cH СH, t + these Propagafion steps goes on repeatef mumber uf times) many Terminahion: +

a) Rea tive intermeliafe 1s a molecular entity (may be ton/molecule) that is from the Teactant and further undergo chemital change to give products be formed in formed It dep of the reaition and usually have a longer Gfe time than a mole cular vibrahon. A nd they are seldom icolated any g:in substitufion reachions of tertary halides, tertiary Carbo cahion alkyl i an intermediate. CH2 (t)cd + Ko intermediate

b Torsional Arain edipeing strain, which molecule Torfional strain 1s an increafes the potential due to repulsions between the electrons im bonds thot were mot direcfy of a enery Connected This strain can be visualised by taking Canformations of mae cules irto account. eg:im Canformahons of ETHANE CH-CH) f the Hydro gens present on two Carbory ovenlmps/eslipses then # leads to torsions strain. #'s not eclipsed- no torsionstrain
