context_page_description: F number is a correlation number used in the analysis of polycyclic aromatic hydrocarbons as a descriptor of their hydrophobicity and molecular size. It was proposed by Robert Hurtubise and co-workers in 1977.
context_section_description: For fluorene, there are 6 apparent double bonds (three pi bonds in each side benzene-like ring); the central ring has one secondary carbon and is non-aromatic. Therefore:
