Question: 1. What would be the electron dot structure of carbon dioxide which has the formula CO2?
Question: 2. What would be the electron dot structure of a molecule of sulphur which is made up of eight atoms of sulphur? (Hint The eight atoms of sulphur are joined together in the form of a ring.)
Question: 3. How many structural isomers can you draw for pentane?
Pentane has three structural isomers. These are n-pentane, Iso-pentane and neo-pentane. Structures of all the three isomers are given here.
Question: 4. What are the two properties of carbon which lead to the huge number of carbon compounds we see around us?
Carbon can form huge number of carbon compounds because of the following properties:
(a) Catenation: Carbon can form bond with other carbon atoms. This property is called catenation. Because of catenation, carbon can form long chains, branched chains and closed chains.
(b) Carbon can form compounds with elements of many other elements.
Question: 5. What will be the formula and electron dot structure of cyclopentane?
Formula of cyclopentane is C5H10
