Deduce the molecular formula of compound T.
Compound T is a colourless liquid. State the colour change when excess compound T is added to aqueous bromine. from [BLANK] to [BLANK]
Compound T can be oxidised to a carboxylic acid. Suggest a suitable oxidising agent for this reaction.
Compound T can be polymerised. Draw the partial structure of the polymer of compound T. Show two repeat units.
Compound T reacts with methanoic acid, $\text{HCOOH}$, to form an ester. Complete the structure of this ester to show all the atoms and all the bonds.
Methanoic acid is a weak acid. Hydrochloric acid is a strong acid. Give the formula of the positive ion that is present in all acids.
Explain why the rate of reaction of $1.0\,\text{mol dm}^{-3}$ methanoic acid with magnesium is less than the rate of reaction of $1.0\,\text{mol dm}^{-3}$ hydrochloric acid with magnesium.
Construct the equation for the reaction of methanoic acid with magnesium.
