Question

I would appreciate help on both of these questions.

C. H. So, 11.0 13. Which of the following is the reverse of halogen abstraction in a radical mechanism? 1) MCPBA: 2) H0 a. hydrogen abstraction b. homolytic cleavage c. elimination the reverse of halogen abstraction in a radical mechanism? d. coupling e. halogen abstraction I 14. Which sequence of reagents would efficiently transform Butane, CH,CH,CH2CH3, to 2- butene, CH,CH=CHCH,? a. 1) Cl, hv; 2) NaOH b. 1) NBS, O C; Na(s)/NH() ould officiently transform Butane, CH CH CH CH. to 2 c. 1) 12, hv; 2) NaoMe d. 1) Br2, 4; 2) t-BuOK/ t-BUOH e. 1) Br, hv; 2) NaOet

Answer 1

Halogen Abstraction : bed and atom In this case what happens fiestly a lodical will abstract a halogen & then generates new ladical. This is very Sorbal to hydrogen abstraction but only a haloger dom is being abstrache not hydrogen at So levase of Halogen abstraction is a Halogen abstraction. & Homolytic devage is devuse of the coupling. addition of pi-bonding juga bevelse of the elimination 36 (14) Ell-Ely - 111₂ - City (ally - CH = CH – CH3 2) Nach go butene.
