Free radicals can be defined as chemical species which have a single unpaired electron. In the important case (for organic chemistry) of the methyl radical, the radical center is trivalent and trigonally hybridized (Scheme 1). The sp2 hybridized carbon atom and the three hydrogens are coplanar and the unpaired (odd) electron occupies a 2p carbon atomic orbital (AO), here arbitrarily designated as 2pz.
2. Acetate fiber is the man-made fiber that is made of cellulose acetate, which is the acetic acid ester of cellulose. It has a very long history, and was first produced in 1923 by an English company, Celanese, in the form of diacetate silk.. Acetate fiber is produced by reacting high purity wood pulp with acetic anhydride. The acetate flakes that are produced through this chemical reaction are dissolved in a solvent, filtered, and adjusted to obtain spinning stock solution.
