Chapter Summary

--- PAGE 1 --- CHAPTER 4 Carbon and its Compounds 1064CH04 In the last Chapter, we came to know many compounds of importance to us. In this Chapter we will study about some more interesting compounds and their properties. Also, we shall be learning about carbon, an element which is of immense significance to us in both its elemental form and in the combined form. Activity 4.1 * Make a list of ten things you have used or consumed since the morning. * Compile this list with the lists made by your classmates and then sort the items into the adjacent Table. * If there are items which are made up of more than one material, put them into both the relevant columns of the table. Things made Things made Others of metal of glass/clay Look at the items that come in the last column of the above table filled by you – your teacher will be able to tell you that most of them are made up of compounds of carbon. Can you think of a method to test this?…
