1

Alkenes have the general formula of CnH2n+2

Select one of the following:

True
False

Explanation

Fill the blank space to complete the text.

Because alkenes contain at least one double bond between carbon atoms, we describe them as compounds.

Explanation

Question 9 of 19

1

The test for ❌ makes use of the ❌ reaction, and involves adding bromine water to a sample of hydrocarbon. If an ❌ is present the solution stays ❌, but an ❌ will turn the solution colourless. This is because the bromine is added across the carbon-carbon ❌ bond.

Question 12 of 19

1

Fill the blank spaces to complete the text.

DNA is a made from four different monomers called . Most DNA molecules are made from two polymer chains. These polymer chains join together in the shape of a . Each nucleotide is made of a sugar molecule, a base (A, C, T or ), and a phosphate group.

Explanation

Question 13 of 19

1

Most ethanol is made from plants, making it a renewable resource. The process is called fermentation, and requires: (check all that apply)

Select one or more of the following:

water
yeast enzymes
an absence of oxygen
temperatures between 25 - 35 °C
ethanol
carbon dioxide

Explanation

Question 14 of 19

1

Fermentation will produce a dilute solution of ethanol, and needs to be purified to remove water and other liquids, as well as insoluble substances, to produce pure ethanol.

Select one of the following:

True
False

Explanation

Question 15 of 19

Question 16 of 19

1

Which of the following is a reaction that alcohols can do?

Select one of the following:

react with metals to form a salt and hydrogen
react with bases to form a salt and water
react with carbonates to form a salt, water and carbon dioxide
will react with the alkali metals to produce hydrogen and a metal hydroxide

Explanation

Question 17 of 19

1

People are concerned the small size of ❌ makes it possible to breathe them in, or to pass into ❌ - once inside the ❌, they might catalyse reactions that are harmful producing ❌ substances. Modern ❌ materials have not been used for long, so it is ❌ for scientists to determine their risks.
