The cards Question What is a functional group? Tap to flip Answer The atom or group of atoms responsible for the way a compound reacts. Question What makes a compound unsaturated? Tap to flip Answer It contains at least one carbon-carbon double covalent bond. Question What are isomers? Tap to flip Answer Structures with the same molecular formula but a different arrangement of atoms in space. Question What is the functional group of the alkenes? Tap to flip Answer C=C, the carbon-carbon double bond. Question What happens to an alkene's saturation when it reacts at its C=C group? Tap to flip Answer It changes from an unsaturated to a saturated molecule. Question How does the boiling point of an alkene change as the alkene gets larger? Tap to flip Answer It gets higher. Question Why do alkenes tend to burn with smoky flames? Tap to flip Answer Because of incomplete combustion. Question What is the shortest alkene? Tap to flip Answer Ethene. Question What functional group do alcohols contain? Tap to flip Answer The -OH group. Question What is fermentation? Tap to flip Answer A process in which the anaerobic respiration of microorganisms turns sugar into a solution of ethanol. Question Do alcohols need more or less oxygen than equivalent alkanes to burn completely? Tap to flip Answer Less. Question Do alcohols mix with water? Tap to flip Answer Yes. They are good solvents that also mix with water. Question How does the boiling point of ethanol compare with that of ethane? Tap to flip Answer Ethanol's boiling point is much higher. Question Which route to ethanol is renewable: fermentation of glucose or hydration of ethene? Tap to flip Answer Fermentation of glucose. Question What is the molecular formula of ethanol, as opposed to its structural formula C₂H₅OH? Tap to flip Answer C₂H₆O. Question What is a homologous series? Tap to flip Answer A family of organic compounds with the same general formula, similar chemical properties and trends in physical properties. Question What is viscosity? Tap to flip Answer How easily a liquid flows: the higher the viscosity, the less easily it flows. Question What colour change does bromine water show with an alkene? Tap to flip Answer Orange to colourless. Question How does the energy released on combustion change as chain length increases? Tap to flip Answer More energy is released. Question How does the viscosity of alkanes, alkenes and alcohols change as chain length increases? Tap to flip Answer It increases. Question What functional group do carboxylic acids contain? Tap to flip Answer The -COOH group. Question Are carboxylic acids strong or weak acids? Tap to flip Answer Weak acids. Question What is a weak acid? Tap to flip Answer An acid that only partially dissociates to form H⁺ ions in solution. Question What forms when ethanol is oxidised? Tap to flip Answer Ethanoic acid. Question What does a carboxylic acid produce when it reacts with a carbonate? Tap to flip Answer A metal salt, carbon dioxide and water. Question What functional group do esters contain? Tap to flip Answer The -COO- group. Question Which alcohol and carboxylic acid make the ester ethyl ethanoate? Tap to flip Answer Ethanol and ethanoic acid. Question What are polymers? Tap to flip Answer Long-chain molecules formed by joining monomers together. Question How many products form in addition polymerisation? Tap to flip Answer Only one: the polymer. Question What polymer forms from the addition polymerisation of ethene? Tap to flip Answer Poly(ethene). Question What is a repeating unit? Tap to flip Answer The section of a polymer that repeats. Question Which bond do monomers for addition polymers contain? Tap to flip Answer C=C, a carbon-carbon double bond. Question What must be drawn at each end of a polymer's repeating unit? Tap to flip Answer Open bonds, showing how the repeating units bond to each other. Question What is landfill? Tap to flip Answer A waste disposal site where waste is buried between layers of soil and other unreactive material. Question Which polymer identification codes do recyclable polymers normally have? Tap to flip Answer Code 1 or 2. Question Give one problem associated with polymers. Tap to flip Answer E.g. availability of raw materials, landfill or combustion. Question What are the monomers of DNA? Tap to flip Answer Nucleotides. Question How many polymer chains does DNA contain? Tap to flip Answer Two, in a double helix. Question What monomer are starch and cellulose made from? Tap to flip Answer Glucose. Question What do amino acids join together to form? Tap to flip Answer Polypeptides and proteins. Question What type of bond do polypeptides contain? Tap to flip Answer Peptide bonds. Question How many functional groups does an amino acid contain? Tap to flip Answer Two.

How this deck was checked On 2026-11-02, every card was compared with its source: the lessons of Oak National Academy, a public body funded by England's Department for Education that publishes lessons for the national curriculum. Because the cards come from those lessons, no second source was sought. The comparison was done automatically, not by a teacher, so a card can still be wrong. Flash Feed is not affiliated with any source named here.
