结果1 题目 The groups that consists of oxygen and carbon joined by a double bond is called the carbonyl group. If the carbonyl group is at the end of the molecular skeleton it is called a(n) 相关知识点: 试题来源: 解析 aldehyde. 反馈 收藏 ...
Carbon-oxygen double bondPseudographic structureSodium-ion batteriesAnodeOxygen-containing functional groups and pseudographic structure are key factors that affect the electrochemical properties of biomass derived carbon materials. In this work, the shaddock peel derived hard carbon with abundant carbon-...
A strong linear relationship was observed between the average double bond equivalence (DBE) and the ratio of carbon to oxygen atoms in oxygenated compounds of dissolved organic matter (DOM). Data were acquired by a Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR MS), equipped ...

260 Recently, the same authors have found that the polymerization of isobutylene by AlEtCl2 was totally inhibited by the simultaneous presence of a hindered pyridine (to prevent cocatalysis) and of oxygen. This effect was claimed to prove that the mechanism of direct initiation involved the ...

we demonstrated the applicability of various nucleophiles such as halides, oxygen, sulfur, phosphorous and carbon nucleophiles for the synthesis of β-substituted trifluoropropylamines. The developed methodology offers a versatile synthetic tool to build high structural diversity on trifluoropropyl backbone...
