Question

DEFINE:- Tetravalency, hydrogenation with example

Answer 1

tetravalency is the ability to form a covalent bond with more than three elements ex: carbon is tetravalent

Answer 2

Tetravalency is the property exhibited by mainly 14th group Most Common example is Carbon It has 4 valence electrons and need more 4 to complete it's octate state . So elements with valency 4 are called as Tetravalent elements
Hydrogenation is addition of Hydrogen to an unsaturated compounds it Unsaturated compound reacts with Hydrogen in presence of Pd or Ni or Pt and results in breaking of bond and it make compound Saturated
