What is the pKa of carbamate?
The ionization of the proton positioned on the carbamate functionality was confirmed spectrophotometrically (pKa = 10.1). The spectrophotometric result was in excellent agreement with that obtained from the solubility studies (pKa = 10.2).
What does high pKa mean?
The higher the pKa of a Bronsted acid, the more tightly the proton is held, and the less easily the proton is given up. The pKa scale as an index of proton availability. Low pKa means a proton is not held tightly. pKa can sometimes be so low that it is a negative number! High pKa means a proton is held tightly.
What is the pKa value of carbazole?
An approximated pKa value for carbazole, between those of indole and pyrrole (-2.4 and -3.8), indicates that the environmental chemistry of carbazole will involve only the free base.
What kind of hydrocarbon is a fluorene leaf?
Fluorene is an ortho-fused tricyclic hydrocarbon that is a major component of fossil fuels and their derivatives It is an ortho-fused polycyclic arene and an ortho-fused tricyclic hydrocarbon. Fluorene is a white leaflets.
What are the uses of the chemical fluorene?
IDENTIFICATION AND USE: Fluorene forms small, white, crystalline plates; it is fluorescent when impure. Derivatives of fluorene show activity as herbicides and growth regulators. It is used as a chemical intermediate. Fluorene occurs ubiquitously in products of incomplete combustion; it also occurs in fossil fuels.
Where does carbazole occur in the combustion process?
Carbazole occurs in coal, petroleum, peat(1), crude oils and coal tar(2). Carbazole occurs in products of incomplete combustion of nitrogen containing organic matter(1,2).
