Inductive electron withdrawal 中文

WebIn this work, we would like to study the substituent effects of NH 2 and NO 2 groups on benzene using Kohn–Sham density functional theory. As is known, these two substituents have completely opposite electronic properties and therefore, opposite effects on the electrophilic substitution reactions of benzene. 1 The amino group is activating and ortho … Web21 rijen · 英文翻譯. 出處/學術領域. 拉電子基團. electron-withdrawing group. 【化學名詞- …
