Understand the application of "isotope tracer method" in studying organic reaction process. Course introduction 1. Write the structural formula of the following groups: hydroxyl aldehyde carboxyl amino alkyl 2. Groups in organic matter have different structures and properties, and they are uncharged. The first scientist to put forward the concept of group was 3. Write the photo-substitution reaction equation of methane and chlorine: ; . Query discussion 1. Study on organic matter structure 1. Groups in organic matter have different structures and properties, and they are uncharged. For example: -—COOH is acidic; -NH2 is alkaline, and the properties of organic matter can be regarded as the sum of the properties of various groups. 2. NMR spectra-determining the structure of organic compounds In NMR vibration analysis, the most common is to analyze the 1H NMR spectra of organic compounds. Different chemical environments (nearby groups) of H nuclei in organic molecules show different nuclear magnetic resonance, and the positions of abscissas (chemical shifts) of peaks representing nuclear magnetic resonance characteristics in NMR spectra are also different. For example, the nuclear magnetic resonance of two organic compounds with molecular formula of C2H6O 1H * * * vibration spectrogram (textbook P9):: Related information:: 1.2 Study on composition and structure of organic matter (elective 5) Courseware Su Jiaoban 2.3.3 Study on chemical equilibrium image (elective 4) Courseware Su Jiaoban/KLOC.
