Question

Why Sulphur shows catenation to a greater extent than oxygen ?

Answer 1

the ability of an element to catenate is primarily based upon the Bond energy of the element to itself. this ability is also influenced by a range of steric and electronic factors, including the electronegativigy of the element.
so as sulphur can form multiple bonds,it shows catenation.
S-S bond is strong enough for sulphur to exhibit catenation properties.,but peroxide linkage is very unstable and easily breakable .hence O-O Bond is very weak and hence, catenation is not exhibited in oxygen.

hope this helps ....!!!
