In a science quiz competition, Deepti asked a question where she had to choose the statement which was/were incorrect?

The diamond crystal is, therefore, made up of carbon atoms which are powerfully bonded to one another by a network of covalent bonds. The melting point of diamond is also very high, being more than 3500°C. Diamond is a conductor of electricity as there are ‘free electrons’ in a diamond crystal. None of the above.

Which of the following does not belong to the same homologous series?

CH4 C2H6 C3H8 C4H8

Badal appeared in class test but he confused to know the correct statement. Would you help him to know that?

If we burn diamond in oxygen, then only carbon dioxide gas is formed and nothing is left behind. Diamond does not conduct electricity. Diamond and graphite are the two common allotropes of carbon which are known to us for centuries. All the above.
