Question

why silicon-silicon bond is weak while carbon-carbon bond is strong?

Open in App

Solution

The size of silicon is big as compared to carbon. The bond is long in silicon and can easily break but in case of carbon , the bond is short and strong . Hence , the bonding is carbon is more strong than silicon. Therefore , the carbon shows strong catenation and forms a large number of compounds.

Q. Assertion :Catenation is the ability of an atom to form bonds with other atoms of the same element. It is exhibited by both carbon and silicon. Reason: Carbon exhibits catenation much more than silicon or any other element due to its smaller size which makes the

bonds are comparatively weaker due to its large size and therefore,

S i

does not have enough bond strength to hold together large molecules.
