在有機化學中,酮-烯醇互變異構(Keto-Enol Tautomerism)是指因酮或醛和烯醇之間的化學平衡。酮或醛和烯醇稱為互變異構體。此平衡出現的原因是,酮和醛等羰基化合物具有酸性的α-質子,在不同的PH值下進行質子的轉移,形成酮式和烯醇式。所以,烯醇式是酮和醛的一種存在形式,不同的酮在溶液中,有不同的烯醇...
互變異構現象是指某些化合物中的一種官能團改變其結構成為另一種官能團異構體且能迅速地相互轉換,兩種異構體處在動態平衡中,這種現象就稱為互變異構現象,簡稱互變異構(Tautomerism),這兩種異構體稱為互變異構體。2.立體異構:結構相似,但由於微小偏差導致結構不同。具體又可分為構型異構和構象異構 構型異構:(1...
