- Which of the following is a second chain propagation step in the free radical chlorination of ethane? A. Cl· + Cl· + hv → Cl2 B. CH;CH2• + •CI → CH3CH2CI O C. Cl2 → 2Cl· D. CH3CH2• + Cl2 → CH3CH2CI + Cl• O E. CH3CH2 •+ • CH2CH3 CH2CH3 - CH3CH2CH2CH3arrow_forwardConsider this reaction: Br CH3OH Br-Br H3CO The mechanism proceeds through a first cationic intermediate, intermediate 1. Nucleophilic attack leads to intermediate 2, which goes on to form the final product. In cases that involve a negatively charged nucleophile, the attack of the nucleophile leads directly to the product. H. Br + CH;OH Br Intermediate 2 (product) Intermediate 1 In a similar fashion, draw intermediate 1 and intermediate 2 (final product) for the following reaction.
