Neco 2024 Chemistry Question 2 diagram

The diagram shows the Lewis structure of methanol, \(\text{CH}_{3}\text{OH}\).

Question Parts

( a )
Identify the central atom in the molecule and state its group number and period in the periodic table.
( b )
Discuss the type of bond formed between the central carbon atom and the attached oxygen atom. Justify your answer using electronegativity values.
( c )
Compare the acidity of methanol with that of water. Using periodic trends, explain which of the two is the stronger acid and why.
( d )
When methanol combusts completely in oxygen it forms carbon dioxide and water.\n(i) Write the balanced chemical equation for the combustion of methanol.\n(ii) Calculate the number of moles present in 1.00 g of methanol.\n(iii) Using the stoichiometry of the balanced equation, determine the mass of carbon dioxide produced from 1.00 g of methanol. (Molar masses: C = 12.01 g mol⁻¹, H = 1.008 g mol⁻¹, O = 16.00 g mol⁻¹).
( ) Balanced combustion equation.
( ) Moles of methanol in 1.00 g.
( ) Mass of CO₂ produced.
