Question

Name the product of the following reaction. cis-3-Hexene. trans-3-Hexene. 1-Hexene. trans-2-Hexene. cis-2-Hexene. Addition of 2 mol of HCl to 1-butyne would yield: CH_3CH_2CH_2CHCl_2 CH_3CH_2CCI_2CH_3 CH_3CH_2CHCICH_2Cl CH_3CH_2CH=CHCI CH_3CHCICHCICH_3 In the presence of excess hydrogen bromide, what is the major product of the addition of HBr to acetylene? 1, 3-dibromoethane 1-bromoethane 1, 1-dibromoethane 1, 2-dibromoethane 2-bromoethane Which of the following compounds is the major product when 1-hexyne is treated with excess HBr? 1, 1-dibromohexane 1, 1-dibromohexene 1, 2-dibromohexene 1, 2-dibromohexane 2, 2-dibromohexane

Answer 1

CH_3 - CH_3 - C equiv CH - CH_2 CH_3 pd, Baso_4 in Downarrow Linsalar's Catalyst vuinoline rightarrow lis product lis - 3 - Hexene 2 mol of HCl to butyne option (c) correct H- C equiv C - H + H Br rightarrow 1, 1 - diloromo ethane CH_3 - CH_2 - CH_2 - CH_2 - C equiv C - 11 excess H Br rightarrow CH_3 - CH_2 - CH_2 - CH_2 - CH_2 CH_3
