Chrysanthemic acid occurs as a mixture of esters in flowers of the chrysanthemum(pyrethrum) family. Reduction of chrysanthemic acid to its alcohol (Section 17.6A) fol-lowed by conversion of the alcohol to its tosylate gives chrysanthemyl tosylate. Solvoly-sis (Section 9.2) of the tosylate gives a mixture of artemesia and yomogi alcohols.
Chapter 1. Matter and Energy Matter Anything that occupies space and has weight, therefore it has volume and mass. States of Matter Solid; Fixed shape and volume, may be soft or hard, and rigid or flexible, particles are close together and organized Liquid; Vary in shape, take the shape of the container, particles close together but disorganized Gas; No fixed shape or volume, Particles farther apart and disorganized. Properties The characteristics that give each substance a unique identity. Types of properties; Intensive properties. They are properties that do not depend on the amount of materials present. They never change (constant). They include boiling and melting points, densities, viscosity, etc. Extensive properties. These are properties that depend on the amount of materials present. They change for example masses, volumes, radii, heights etc. Changes Physical changes; Particles before and after remain the same No change in composition For example liquids to solids or to gasses Chemical changes; Particles before and after are different Change in composition For example if an electric current is applied on water, it breaks down to oxygen and hydrogen gas. Energy It is the ability to do work. Energy is divided into two types i.e. Potential energy; Energy due to position of an object. It is how high or low and object is. Kinetic energy; Energy due to m
