Question 7 Answer saved Marked out of 5.00 Which of the following will be the principle product of the reaction between methylenecyclopentane and hydrogen bromide in the presence of peroxides? HBr, ROOR methylenecyclopentane Flag question Select one RO RO Question 8 Not yet answered Marked out of 5.00 During the reaction of molecular bromine with 2,2,3-trimethyl pentane hydrogen atom will be abstracted from Select one a. carbon number 1 of the parent chain o b. carbon number 3 of the parent chain O c. carbon number 5 of the parent chain o d. carbon number 4 of the parent chain O e. carbon number 2 of the parent chain O f. carbon of the methyl groups at position 3 o g. either carbon of the two methyl groups at position 2 Flag question

Explanation / Answer

7) Peroxide causes Br addition to less substituted side of double bond. Hence 1- C

8) Hydrogen will be abstracted from tertiary carbon which has Hydrogen. Hence carbon 3 which has tertiary hydrogen will be abstratced, Hence 2- b

9) Propagation step

Propagation step

Initiation step

Termination step
