why sulphur catenation property whereas oxygen does not

The ability of an element to catenate is primarily based on the bond energy of the element to itself. This ability is also influenced by a range of steric and electronic factors, including the electronegativity of the element.

so as S can form multiple bonds , it shows catenation.

S-S bond is strong enough for sulfur 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.
