Here are the solutions based on the image provided: 1. Reaction of Ethene with Hypobromous Acid (HOBr) Step 1: Identify the reactants and product. Ethene (CH_2=CH_2) reacts with hypobromous acid (HOBr) in an electrophilic addition reaction. The double bond breaks, and the -OH and -Br groups add across the carbon atoms. Step 2: Write the balanced chemical equation using structural formulas. & H H \\ & | | \\ H-C&=C-H + HO-Br → H-C-C-H \\ & | | \\ & H H OH Br The product formed is 2-bromoethanol. 2. Oxidation of Ethene with Potassium Tetraoxomanganate(VII) Step 1: Identify the reactants and product. Ethene (CH_2=CH_2) is oxidized by nascent oxygen ([O]) from dilute, cold potassium tetraoxomanganate(VII) (KMnO_4) in the presence of water (H_2O). This reaction is known as Baeyer's test and results in the formation of a diol. Step 2: Write the chemical equation for the reaction. & H H \\ & | | \\ H-C&=C-H + H_2O + [O] dilute, cold KMnO_4 H-C-C-H \\ & | | \\ & H H OH OH The product is ethane-1,2-diol (also known as ethylene glycol). 3. Definition of Polymerisation Reaction Step 1: Define polymerisation. Polymerisation is a chemical process in which many small, repeating molecules, called monomers, react together to form a very large chain-like molecule, known as a polymer. Step 2: Explain the nature of the process. During polymerisation, the monomers link together through covalent bonds, forming a macromolecule with repeating structural units. The definition is: A polymerisation reaction is a chemical process where numerous small molecules, called monomers, combine to form a large, chain-like molecule known as a polymer. The monomers link together through covalent bonds to create a repeating structural unit within the polymer. Send me the next one 📸
