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.
Acetate fibers are the manufactured fibers in which the fiber-forming substance is cellulose acetate. The cellulose esters triacetate and acetate are formed through acetylation of cotton linters or wood pulp using acetic anhydride and an acid catalyst in acetic acid. Cellulose is an excellent fiber. 2  Cellulose is made of repeat units of the monomer glucose. 3  The three types of regenerated cellulosic fibres are rayon, acetate and triacetate which are derived from the cell walls of short cotton fibres called linters.
