The discussion centers on the chemical phenomenon of hyperconjugation and its relationship to coordinate bonding. Participants clarify that hyperconjugation involves the donation of electron density from a pi bond into an adjacent sigma antibond, which differs from coordinate bonds that typically involve the donation of a full electron pair from a Lewis base to a Lewis acid. While hyperconjugation and coordinate bonding share similarities, they are fundamentally different in nature, with hyperconjugation being more about electron density distribution rather than the formation of a distinct bond.
PREREQUISITESChemistry students, organic chemists, and anyone interested in the nuances of chemical bonding and molecular interactions.
I agree with TeethWhitener. I don't think a hyperconjugative interaction qualifies as a bond in the first place. But you likely learned in gen chem that a coordinate (or dative) covalent bond is a bond that was formed from a 2 e- interaction between a lewis acid and a lewis base. However, if you just look at a molecule by itself, e.g. CCl4, you can't say whether the bonds are dative or not. This molecule could be made from radicals or ions. Cl- + Cl3C+ --> CCl4 but Cl. + CCl3. -->Karan Punjabi said:Guys, a certain chemical phenomenon known as hyperconjugation in which carbonium ion which is tertiary or secondary or primary in nature then the pi bond formed for stabilizing effect can be defined as a co ordinate bond or not?
