Work out the Question Paper-5, Variant 2 Summer (May-June) 2013.
Subject code: 9702
Website: www.xtremepaper.com
Chapter's Name: Chemical Bonding
Reading Instruction:
Study the properties of covalent compounds
Task:
The elements carbon and silicon are both in Group IV of the Periodic Table.
Carbon is the second most abundant element by mass in the human body and silicon is the second
most common element in the Earth’s crust.
Carbon and silicon each form an oxide of general formula XO2.
At room temperature, CO2 is a gas while SiO2 is a solid with a high melting point.
(a) Briefly explain, in terms of the chemical bonds and intermolecular forces present in each
compound, why CO2 is a gas and SiO2 is a solid at room temperature.
[3]
(b) Draw a simple diagram to show the structure of SiO 2. Your diagram should contain at least
two silicon atoms and show clearly how many bonds each atom forms.
