WebAfter the formation of a carbocation, the one more stable is generally referred to as the one that is less reactive.. Reactions when proceed spontaneously are mainly driven by the …
WebSolution. A carbanion is a nucleophile, which stability and reactivity determined by several factors: 1) The inductive effect. Electronegative atoms adjacent to the charge will stabilize the charge . 2) Hybridization of the charge-bearing atom. The greater the s-character of the charge-bearing atom, the more stable the anion . WebThe stability of radicals is as follows. Tertiary > Secondary > Primary; The reason for this order of radical stability is the effect of hyperconjugation. In other words, the stability of radicals can be explained by exactly the …
