Question 1 Report

(a) Name the type of solid structure possessed by:

(i) diamond;

(ii) iodine;

(iii) sodium chloride.

(b) Give:

(i) one alloy of tin:

(ii) a common reducing agent which is a compound of tin.

Answer

Answer Details

(a) Type of solid structure

(i) Diamond: giant covalent (atomic/macromolecular) structure. Each carbon atom is covalently bonded tetrahedrally to four other carbon atoms.
(ii) Iodine: simple molecular (molecular crystal) structure. Discrete \(I_2\) molecules are held together in the lattice by weak van der Waals forces.
(iii) Sodium chloride: giant ionic (ionic crystal) structure. \(Na^+\) and \(Cl^-\) ions are held in a regular lattice by strong electrostatic (ionic) forces.

(b)

(i) One alloy of tin: solder (an alloy of tin and lead). Other acceptable answers are bronze (tin and copper) or pewter (tin, antimony and copper).
(ii) A common reducing agent that is a compound of tin: tin(II) chloride, \(SnCl_2\). The \(Sn^{2+}\) ion is readily oxidized to \(Sn^{4+}\), so it acts as a reducing agent.
