Quick Q&A Before You Revise
Why does carbon not usually form ionic compounds?
Carbon would need to gain or lose four electrons, which is difficult, so it usually forms covalent bonds by sharing electrons.
What is the easiest way to spot an unsaturated compound?
Look for a double bond or triple bond between carbon atoms.
Why are esters important in this chapter?
They connect equations with observation because they have pleasant smells and are formed in a named reaction.
Do all carbon compounds burn?
Many carbon compounds are combustible, but the reaction conditions and completeness of burning can vary.
Why is ethanoic acid called acidic?
It releases hydrogen ions in aqueous solution and shows acidic behaviour with indicators and bases.
Why does soap form scum?
Soap reacts with calcium and magnesium ions in hard water to form insoluble salts called scum.
What should I memorise from homologous series?
Remember the pattern of names, formulas, and the CH2 difference between consecutive members.
Can detergents replace soaps completely in explanations?
No. The chapter expects students to compare both and explain why detergents perform better in hard water.
