Polynuclear hydrocarbons

2018-09-27 22:22:03 0 ملحق | 1 واجب
Polynuclear hydrocarbons are hydrocarbons—organic compounds containing only carbon and hydrogen—that are composed of multiple aromatic rings (organic rings in which the electrons are delocalized). The simplest such chemicals are naphthalene, having two aromatic rings, and the three-ring compounds anthracene and phenanthrene. إقراء المزيد
