The Palgrave Companion to Oxford Economicse extensions of covalent bonds to these atoms. Through such positive “σ-holes,” the atoms can interact attractively and highly directionally with negative sites such as the lone pairs of Lewis bases, anions, π electrons, etc. In the case of Group?VII this is called “halogen bonding.” Hydrogen bondin作者: Processes 時(shí)間: 2025-3-22 02:24
