This document discusses tests for phenol in organic and natural chemistry. It addresses the qualitative examination for phenol according to the PCI syllabus for your third semester of the B.
Sachse-Mohr theory proposes that cyclic compounds like cyclohexane are certainly not planar rings with strained carbon-carbon bonds, but alternatively exist in puckered, 3-dimensional conformations that enable the carbon atoms to take care of their standard tetrahedral geometry and bond angles of 109.
The document discusses 12 chemical compounds known as the "Dirty Dozen" and nine chemicals generally known as the "Nasty Nine" that are persistent organic pollutants.

They include things like aldrin, chlordane, DDT, and dioxins.
……我一直在研究煤焦油里的化学基团和取代物，也有了不少科学发现，但据我所知，都没有什么商业价值。一天晚上，我做实验做得太起劲儿，很晚了才急匆匆地去吃晚饭，而且还没洗手。我坐下掰了一块面包塞进嘴里，感觉甜得难以言喻。我也没多想，以为是沾了蛋糕或者果脯。我去漱了漱口，用手巾擦嘴，可这手巾竟然比面包还甜。这下我就不理解了。我又往杯子里灌水，冲洗我嘴上被我的手指碰过的地方。那水就像糖浆一般甜。我突然想到，前前后后这所有甜味都是我引起的，于是我舔了舔大拇指尖，果然是甜过这世上所有的甜品。我立马就懂了，我从煤焦油里发现或发明了一种超越任何糖的糖类。我也不吃晚饭了，一溜烟跑回实验室，兴奋地把烧杯和蒸发皿都尝了一个遍。万幸里面没有任何腐蚀性或有毒的液体。
Swithers and Davidson within their research mentioned that sweet preferences Typically suggest that the body is going to receive a substantial range of energy, as well as digestive method prepares to react accordingly.
