  1. 1Alkenes have the general formula of CnH2n+2
    1. AVerdadeiro
    2. BFalso
  2. 2Because alkenes contain at least one double bond between carbon atoms, we describe them as [blank_start]unsaturated[blank_end] compounds.
    1. Aunsaturated
  3. 3The test for [blank_start]alkenes[blank_end] makes use of the addition reaction, and involves adding [blank_start]bromine[blank_end] water to a sample of hydrocarbon. If an [blank_start]alkane[blank_end] is present the solution stays orange-brown, but an [blank_start]alkene[blank_end] will turn the solution colourless. This is because the bromine is added across the carbon-carbon [blank_start]double[blank_end] bond.
    1. Aalkenes
    2. Balkanes
    3. Cbromine
    4. Dchlorine
    5. Eiodine
    6. Falkane
    7. Galkene
    8. Hdouble
    9. Isingle
  4. 4Alcohols have the functional group of [blank_start]-OH[blank_end] ([blank_start]hydroxyl[blank_end]), and gives rise to the ending of alcoh[blank_start]ol[blank_end]. It is responsible for the general reactions that all alcohols can do.
    Carboxylic acids have the functional group of [blank_start]-COOH[blank_end] ([blank_start]carboxyl[blank_end]), and gives rise to the ending of carbox[blank_start]ylic acid[blank_end]. It is responsible for the general reactions that all carboxylic acids can do.
    1. A-OH
    2. Bhydroxyl
    3. Col
    4. D-COOH
    5. Ecarboxyl
    6. Fylic acid
  5. 5Which of the following is not a reaction alcohols can do?
    1. Acan be oxidised to make a carboxylic acid in the presence of an oxidising agent
    2. Bburn in air to produce carbon dioxide and water
    3. Cdissolve in water to form neutral solutions
    4. Dreact with metals to form a salt and hydrogen
  6. 6What is the name of the polymer formed from monomers of propene?

    [blank_start]poly(propene)[blank_end]
    1. Apoly(propene)
  7. 7Proteins are an example of [blank_start]polymers[blank_end]. There are [blank_start]21[blank_end] different amino acids that can be arranged to make proteins we need to survive. Many proteins are [blank_start]enzymes[blank_end], and/or are essential to our biological functions.
    Amino acids have two different functional groups in a molecule. Amino acids react by [blank_start]condensation[blank_end] polymerisation to produce [blank_start]polypeptides[blank_end].
    1. Apolymers
    2. B21
    3. Cenzymes
    4. Dcondensation
    5. Epolypeptides
  8. 8Match the colours to the metal ionsImagem da pergunta 8
    1. Acrimson
    2. Bred
    3. Cgreen
    4. Dblue
    5. Eyellow
    6. Flilac
    7. Gpurple
    8. Horange-red
    9. Iorange
  9. 9Dilute sodium hydroxide solution (NaOH) is used to test for some metal ions and can also be used to identify ammonium ions. Write the colour of the precipitate formed next to each ion.
    aluminium [blank_start]white[blank_end]
    calcium [blank_start]white[blank_end]
    copper [blank_start]blue[blank_end]
    iron(II) [blank_start]green[blank_end]
    iron(III) [blank_start]brown[blank_end]
    1. Awhite
    2. Bwhite
    3. Cblue
    4. Dgreen
    5. Ebrown
  10. 10Match the chemical test to to the ionsImagem da pergunta 10
    1. Aadd acid, then barium chloride
    2. Badd dilute acid
    3. Cadd barium chloride
    4. Dadd nitric acid, then silver nitrate
    5. Eadd silver nitrate
    6. Fadd nitric acid
