In contrast, the boiling points of PhF and benzene are very similar, differing by only 4 °C. It is considerably more polar than benzene, with a dielectric constant of 5.42 compared to 2.28 for benzene at 298 K. [4] Fluorobenzene is a relatively inert compound reflecting the strength of the C–F bond.
2-Chlorobenzaldehyde (o-chlorobenzaldehyde) is an organic compound with the formula ClC 5 H 4 CHO. It is one of three isomeric monochlorinated benzaldehyde. 3-Chlorobenzaldehyde and 4-chlorobenzaldehyde are the other isomers. Whereas benzaldehyde is prone to autoxidation, the 2-chloro derivatives are more air-stable.
2-Chloro-6-fluorobenzaldehyde is prepared by oxidation of 2-chloro-6-fluorotolulene by chromyl chloride. [3] It reacts with sodium hydroxide to give a mixture of 2-chloro-6-fluorobenzene and 6-chlorosalicaldehyde. [4] 2-Chloro-6-fluorobenzaldehyde is used in the production of the antiseptics dicloxacillin and flucloxacillin.
H 2 C=CH 2 + HCl → CH 3 CH 2 Cl. In oxychlorination, hydrogen chloride instead of the more expensive chlorine is used for the same purpose: CH 2 =CH 2 + 2 HCl + 1 ⁄ 2 O 2 → ClCH 2 CH 2 Cl + H 2 O. Secondary and tertiary alcohols react with hydrogen chloride to give the corresponding chlorides.
Parachlorobenzotrifluoride is a synthetic halogenated organic chemical compound with the molecular formula C 7 H 4 ClF 3. It is frequently abbreviated PCBTF. It is frequently abbreviated PCBTF. Parachlorobenzotrifluoride is a colorless liquid with a distinct aromatic odor.
Diazotization of aniline in the presence of hydrochloric acid: C 6 H 5 NH 2 + HNO 2 + HCl → [C 6 H 5 N 2]Cl + 2 H 2 O. The tetrafluoroborate can be obtained from crude benzenediazonium chloride by salt metathesis using tetrafluoroboric acid. [C 6 H 5 N 2]Cl + HBF 4 → [C 6 H 5 N 2]BF 4 + HCl. The tetrafluoroborate is more stable than the ...
