NEETChemistryp Block Elements (Group 13 & 14)
Why do heavier elements not form pπ– pπ bonds like carbon?
Options
- ABecause they have smaller atomic orbitals.
- BBecause they have too few valence electrons.
- CBecause their atomic orbitals are too large and diffuse to have effective overlapping.
- DBecause they have a higher ionization enthalpy.
Correct answer
C. Because their atomic orbitals are too large and diffuse to have effective overlapping.
Step-by-step solution
Heavier elements do not form pπ– pπ bonds because their atomic orbitals are too large and diffuse to have effective overlapping.
