Heterolysis can generate a (a positively charged carbon intermediate) or a (a negatively charged carbon species). Two sigma bonds are broken and a pi bond is formed between adjacent atoms in reactions. A one-step reaction is called a reaction, while a stepwise reaction involves more than one step, and the staring material is first converted to an unstable intermediate called a intermediate. A reaction replaces an atom or group of atoms with another atom or group of atoms. In an reaction, elements are added to a starting material. A mechanism is a detailed description of how bonds are broken and formed as a starting material is converted to a product. Homolysis generates reactive intermediates with unpaired electrons called radicals, while heterolysis generates intermediates.

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
