ts structural formula indicates whether a hydrocarbon is an allkane, allkene alkyne, or aromatic compound? Show an carban-rarbon (Single band) Carban- carbon (Daoe band)c=C : Carlbon-Corban (tripu band) egample of each. :Bemzene ring 3. Write equations to illustrate the reaction or bromine with these organic compounds (a) Ethane (C2He) (Assume this reaction is done in the presence of light) C 2Hu tBr2- C2H4 Br2 + H2 Single bond (b) Ethylene (C2H4) C2H4 tBr2 C2. Hy Br2-Dabe bnd u - CZH2+Br2 C2H2 Br2 c) Acetylene (C2H2)

Answer 1

Ethane is a saturated compound. So, this undergoes substitution reaction. When Ethane is treated with Bra in presence of light, bromoethane is fromed. hy CH3 -CH2 + Brą - → CH3 -CH2-Br + HBr bromoethane C_HBr Ethene is an unsaturated compound (it contains one double bond). So, this undergoes addition reaction. When ethene is treated with Brı, dibromoethane is fromed. CH2=CH2 + Br2 → Br-CH2-CH2-Br 1,2-dibromoethane C2H_Br2 Acetylene is an unsaturated compound (it contains two double bonds). So, this undergoes addition reaction. When acetylene is treated with Bry, two moles of Br2 adds to acetylene to form tetrabromoethane. CH=CH + 2 Br2 - → Br-CH-CH-Br Br Br 1,1,2,2-tetrabromoethane C2HBr4
