Answer 1

G -oh PBrz Br NaN / Naty Bra COA a trans-organo-dibromide. By I Br Ich Ich 2 3 3 3 4 4 4 4 In Cyclopentane, all Carbon atom is equivalent, So, it will give only one 13C-NMR Peak. Il Methyl cyclopentane contains four types (12,3,4) of Carbon, so it will give four 13 C-NMR peak Similarly, 3-methyl cyclopentene contain four types of carbon & will show four BC-NMR Peak So Correct esption ist ) 1, 4,4 CH3 13 Na, NH3 the - Ching CH3 a) a trans epoxide mpen (combo) m 1114 CHI Trans epoxide
