Answer» ving X as leaving group, + charge develops on C bonded to X.Alkyl: Reference for comparison, Allyl, sp2 hybrid C has high electronegativity. Thus, makes it difficult to BREAK bond(heterolytic cleavage for forming of X-, ) . Positive charge is unstable on more electronegative atom. Using this, allyl are least reactive as sp>sp2,>sp3 (electronegativity and s character).Vinyl C bonded to Sp2 C, when gets positive charge its positive charge is in conjugation with CC π bond does RESONANCE and is thus STABLE so has more TENDENCY to form.Vinyl, Alkyl,allyl |
