NEETChemistryp Block Elements (Group 13 & 14)
What is the reason for the increased tendency to exhibit a +2 oxidation state in heavier members of group 14?
Options
- APresence of d orbital in valence shell
- BHigh ionization enthalpy
- CElectron donation from ns2 electrons
- DFormation of electron precise molecules
Correct answer
A. Presence of d orbital in valence shell
Step-by-step solution
The increased tendency to show +2 oxidation state in heavier members is due to the inability of ns2 electrons of valence shell to participate in bonding, which is because of the presence of d orbitals in them.
