Catenation in carbon is infinite but that in sulphur occurs only upto 8 times. Why?

Answers

Answered by sáķśhâm

It happens because size of the atom increases as you move top to bottom in periodic table.The size of the atom of Sulphur is greater than carbon.Therefore catenation is infinite in carbon atom but that in sulphur occurs only upto 8 times.

Hope u liked it..

divyas1301: And also, why does lithium or beryllium not show catenation ...if they do, then is it infinite? If not, why?

sáķśhâm: The element to element bond energy decreases because of Increase in the size of an atom.So element other than sulphur ,silicon shows less tendency of catenation

sáķśhâm: please explain the question well

divyas1301: Ok - Catenation - it's the linkage of atoms. So from your explanation I understand that for catenation to occur, the atoms held together need to have greater internal force of attraction towards each other than any other possible bond formation. This seems to be possible for carbon. For sulphur, the catenation cannot hold more than 8 atoms because of the larger atomic radius and thus lesser force of attractions between atoms and so 8 is the maximum. Is that right?

sáķśhâm: Yes

divyas1301: Yes! Thanks!

divyas1301: is cyclopentane an isomer to pentane?

sáķśhâm: no

divyas1301: ok - because number of H atoms is changing

sáķśhâm: No because it is a cyclic compound structure not an isomers
