Carbon, in all its allotropic forms, burns in oxygen to give carbon dioxide along with the release of heat and light. Most carbon compounds also release a large amount of heat and light on burning. These are the oxidation reactions
1. Compounds of carbon with hydrogen alone are called as
(i) Hydrocarbons
(ii) Isocarbons
(iii) Allotropes
(iv) Isomers
2. State true or false : Saturated hydrocarbons will generally give a clean flame while burning.
(i) TRUE
(ii) FALSE
3. What is the colour of the Lame given by unsaturated carbon compounds while burning?
(i) Red
(ii) Yellow
(iii) Blue
(iv) Orange
4. Can saturated hydrocarbons give a sooty flame?
(i) Yes
(ii) No
5. Out of the following pairs of compounds, the unsaturated compounds are _______.
(i) \(C_2H_6\) and \(C_4H_6\)
(ii) \(C_6H_{12}\) and \(C_5H_{12}\)
(iii) \(C_4H_6\) and \(C_6H_{12}\)
(iv) \(C_2H_6\) and \(C_4H_{10}\)
