Finding the more stable molecule with the help of Backbonding CONCEPT. I. A molecule with backbonding is more stable than a molecule without backbonding 2. When dealing with two molecules in which Backbonding is present in both, the molecule with stronger backbonding will be more stable.

To find out which one is the better acid. 1. When given to compare the acidic strength of two acids, make their Remove a proton from it) Weaker the conjugate bases, more stronger is the acid. Using this concept look for the backbonding in the acids, the one with more stronger BB will be less acidic. conjugate bases 2. which one of th louloutng ts better acid? CH OR CHF 3 Co ugote Base ce CL No Be, thus weaker
To explain the exceptions in hybaidisation Concept- Due to BB, sometimes the molecule hybridises to lower H. CHy SiH 88 ocaurs Se i^bidisatien
To find the molecule longer bond length. Concept Stronger the back bonding, shorter is the bond length. Arrange tn order a tnereasina Bond length 9 6 >B Neither them BB absenb
