Q17. Write in the boxes, the names of the species in the following reaction of alkyne with bromine. Step 1: Identify the reactants and products. The reaction starts with ethyne (CH) and bromine (Br_2). The first product shown is CH(Br)=CH(Br), which is 1,2-dibromoethene. This product then reacts with another molecule of Br_2 to form CH(Br_2)-CH(Br_2), which is 1,1,2,2-tetrabromoethane. The names of the species are: CH + Br_2 1,2-dibromoethene + Br_2 1,1,2,2-tetrabromoethane Name the following structures (IUPAC) and identify the type of compound: Q18. CH_3-CH(CH_3)-CH_2-CH_3 IUPAC Name: 2-methylpentane Type of compound: Alkane Q19. CH_3-C-CH_3 IUPAC Name: But-2-yne Type of compound: Alkyne Q20. CH_3-CH_2-CH(CH_3)-CH=CH_2 IUPAC Name: 3-methylpent-1-ene Type of compound: Alkene Q21. CH_3-CH(OH)-CH_2-CH_3 IUPAC Name: Butan-2-ol Type of compound: Alcohol Q22. CH_3-CH_2-CH_2-COOH IUPAC Name: Butanoic acid Type of compound: Carboxylic acid PART C: EXTENDED RESPONSES Explain the following terms/phrases. Q21. Fermentation Fermentation is a metabolic process that converts sugar into acids, gases, or alcohol in the absence of oxygen. It typically occurs in yeast and bacteria, and also in oxygen-starved muscle cells, to generate energy. Q22. Polymerization Polymerization is a chemical process where small molecules called monomers react together to form a long chain or network of repeating units called a polymer. This reaction involves the formation of covalent bonds between the monomer units. Q23. Cracking Cracking is the process of breaking down large, complex hydrocarbon molecules into smaller, simpler hydrocarbon molecules. This is typically achieved by applying heat and/or catalysts, and it is used in the petroleum industry to produce more valuable lighter fractions like gasoline from heavier crude oil fractions.
