NCERT In Text Solution
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?
Answer: 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?
Answer: Carbon can form huge number of carbon compounds because of the following properties:
- 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.
- Carbon can form compounds with elements of many other elements.
Question: 5. What will be the formula and electron dot structure of cyclopentane?
Answer: Formula of cyclopentane is C5H10
Question: 6. Draw the structures for the following compounds.
- Ethanoic acid
(i) Ethanoic acid
Question: 7. Are structural isomers possible for bromopentane?
