CAIE A Level Chemistry 9701 · Chemical bonding
The Pauling electronegativity values for sulfur and chlorine are 2.58 and 3.16 respectively.
Explain the difference in electronegativity between these two elements. Use these values to predict the type of bonding in the compound , and explain your reasoning.
4 marks, so the mark scheme is looking for about 4 separate creditworthy points. Making the same point twice in different words earns it once.
Explain means: Give the reasons or the mechanism: why or how something happens. Link each point to the next with because, so or which means. A list of facts with no links usually loses the reasoning marks.
