They are formed from an alcohol and carboxylic acid. An acid catalyst is usually used and the one to know is ETHYLETHANOATE (6) 4. ... are small molecules that contain carbon, oxygen and hydrogen. ... react together through polymerisation reactions to form larger carbohydrate polymers. e.g. Starch and Cellulose (6) 5. ... is made of two polymer chains called nucleotides. They each contain a small molecule- a base. The 4 bases are A,C,T,G. Bases pair up with each other, form cross links keeping the strands together giving the double helix structure (3) 7. ... contain an amino group and a carboxyl group. e.g. Glycine- smallest and simplest. ... can form polypeptides via condensation polymerisation. Amino groups of ... can react with the acid group from another to form a polymer chain (5, 5) 9. Ethanol can be made by ... It uses an enzyme in yeast to convert sugars into ethanol. Carbon dioxide is also produced. Ethanol produced is aqueous. ... happens fastest at 37 degrees in a slightly acidic solution under anaerobic conditions (12) Down 2. First four alcohols have similar ... : They are flammable, they combust completely in air and produce Carbon dioxide and water. They are all soluble in water, have a neutral pH. Alcohols can be oxidised to form a carboxylic acid (10) 3. Alcohols are used as ... They can dissolve most things water can and can dissolve some substances that water can't e.g. Hydrocarbons. First 4 alcohols are used as fuels e.g. Ethanol in spirit burners (8) 6. ... are a homologous series that have COOH as a functional group. Names end in 'anoic acid' e.g. Methanoic Acid, Ethanoic Acid, Propanoic Acid and Butanoic Acid. They react with carbonates to produce a salt, water and carbon dioxide (10, 5) 8. ... polymerisation involves monomers with different functional groups. Monomers react together and bonds form, making polymer chains. For each new bond formed, a small molecule is lost. Simplest types contain two different types of monomers (12)
