    $$Z-\overset{Z}{\overset{|}{\underset{Z}{\underset{|}{X}}}}-\overset{Z}{\overset{|}{\underset{Z}{\underset{|}{X}}}}-\overset{Z}{\overset{|}{X}}=Y$$

    Given here is the structural formula of the compound formed of X, Y and Z elements.

    X is a tetravalent element and exhibits catenation property. Y belongs to group 16 and period 2. Z is the only non-metal present in the reactivity series.

    The next member of homologous series of the above compound is:

  • Question 9
    1 / -0

    Fullerene is an allotrope of carbon which is similar to a football. It has 60 carbon atoms joined together and no other element in it. There are various types of fullerenes. $$C_{60}, C_{70}, C_{74}$$ and $$C_{75}$$ are the members of the fullerene family. But $$C_{60}$$ (pronounced as C sixty) is the most stable and most studied form of fullerenes. What do you think is the nature of the bond which is joining these atoms together?

  • Question 10
