Synthesis and Structural Determination in the General Chemistry Laboratory

一个新的实验，说明合成，键合， 为普通化学实验室提出了结构。 这个实验将利用现代仪器 提出这些概念的结构测定方法 适合新生的水平。学生们将进行一系列 香草醛的微型反应，包括氧化和 醛的还原，芳环的溴化， 和苯酚的酯化。反应物和产物 将通过气相色谱-质谱法进行分析， 红外分光光度法这项实验将服务于每一个 学生在新生班提供一个更平衡的观点 提供了一个替代的切入点， 化学专业。

A new experiment illustrating synthesis, bonding, and structure is proposed for the general chemistry laboratory. This experiment will take advantage of modern instrumental methods of structural determination to present these concepts at a level appropriate for freshmen. Students will run a series of microscale reactions on vanillin, involving oxidation and reduction of the aldehyde, bromination of the aromatic ring, and esterification of the phenol. Both reactants and products will be analyzed by gas chromatography-mass spectrometry and infrared spectrophotometry. This experiment would serve every student in the freshman class by affording a more balanced view of chemistry and providing an alternative entry point into the chemistry major.
