The reactivity of these compounds is very high. The principle is: Na transfers the outermost electrons to the empty orbital of naphthalene to form anionic radicals; then forms an ion pair with Na+, releasing a large amount of resonance energy, and forming a mixed solution of dark green metal organic compounds.064nm) is greater than that of hydrogen atoms (0. The helical conformation just surrounds the PTFE's carbon chain skeleton, which is vulnerable to chemical attack, forming a tight and complete;fluorinated; protective layer, so that the PTFE main chain is not attacked by any exteal reagents, so that PTFE has other materials Unmatched solvent resistance, chemical stability, and low...
