Written in a clear and understandable manner, this book provides a comprehensive, yet non-mathematical, treatment of the topic, covering the basic principles of symmetry and the important spectroscopic techniques used to probe molecular ... Found inside – Page 477A plane of symmetry is an internal mirror plane. As with all other three-dimensional objects, organic molecules are either symmetric or asymmetric. Found inside – Page 235There must be no plane of symmetry in the molecule, no center of symmetry, and no low-energy path for the interconversion of the mirror images. This book is based on very basic knowledge to understand organic chemistry. The basic chemistry of organic compounds is discussed very comprehensively in the book. This seventh edition is extensively revised and enlarged by adding new material to take account of recent developments and extensive amendments have been made to improve clarity.
