Types of Bonding & Properties
1. This question has 4 part(s).
1.1. Sodium and chlorine react together to produce sodium chloride. The bonding in the product is different from that in both of the reactants. Sodium chloride is ionically bonded.
State the meaning of the term ‘ionic bond’.
1.2. Solid boron tribromide has a simple molecular lattice structure. The atoms are held together by covalent bonds.
Draw a ‘dot and cross’ diagram to show the bonding in a boron tribromide molecule.
Show outer electrons only.
1.3. Chloroethylene, C2H3Cl is a chemical binder used in paints and cosmetics.
i) A student stated that there is ionic bonding present in chloroethylene. Justify with reasons, if you agree with this statement.
ii) Draw the ‘dot and cross’ diagram to show the type of bonding present in chloroethylene.
Show outer electrons only.
1.4. A molecule of NH3 reacts with a molecule of BH3 forming ammonia borane, NH3BH3, as shown in the following equation.
NH3 + BH3 → NH3BH3
i) State the type of bond formed between the N atom and the B atom in NH3BH3.
ii) Explain how this bond is formed.
