Reactions of Organic Compounds Crossword Puzzle

QUESTIONS LIST:

• hydration : the addition of the elements of water across a carbon-carbon double bond; h- adds to one carbon, and -oh to the other.
• fractional distillation : a method of distillation using a fractionating column, used to separate liquids with different boiling points.
• alcohols : a series of organic compounds containing the functional group -oh and with the general formula cnh2₂n₊₁oh.
• hydrogenation : an addition reaction in which hydrogen is added across the double bond in an alkene.
• catalytic cracking : the decomposition of long- chain alkanes into alkenes and alkanes of lower relative molecular mass; involves passing the larger alkane molecules over a catalyst heated to 500 °c.
• isomers : compounds that have the same molecular formula but different structural arrangements of the atoms - they have different structural formulae.
• substitution reaction : a reaction in which an atom (or atoms) of a molecule is (are) replaced by different atom(s), without changing the molecule's general structure.
• esterification : the chemical reaction between an alcohol and a carboxylic acid that produces an ester; the other product is water.
• photochemical reaction : a chemical reaction where the activation energy required to start the reaction is provided by light, usually of particular wavelength, falling on the reactants.
• refluxing : a practical technique using a condenser fitted vertically to condense vapours from an experiment back into a flask.
• carboxylic acids : a homologous series of organic compounds containing the functional group -cooh (-co₂h), with the general formula cnh₂n₊₁cooh.
• fermentation : a reaction carried out using a living organism, usually a yeast or bacteria, to produce a useful chemical compound; most usually refers to the production of ethanol.
