Pentane is an organic compound with the formula C 5 H 12 —that is, an alkane with five carbon atoms. The term may refer to any of three structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n-pentane isomer, in which case pentanes refers to a mixture of them; the other two are called isopentane (methylbutane) and neopentane ...
C 5 H 12 O Molar mass: 88.148 g/mol Appearance colorless liquid Density: 0.815 g/ml Melting point: −63.68 °C (−82.62 °F; 209.47 K) Boiling point:
[12] [13] Cyclopentane requires safety precautions to prevent leakage and ignition as it is both highly flammable and can also cause respiratory arrest when inhaled. [14] Cyclopentane can be fluorinated to give compounds ranging from C 5 H 9 F to perfluorocyclopentane C 5 F 10. Such species are conceivable refrigerants and specialty solvents ...
It forms a variety of adducts of the type [CrCl 3 L 3] q+, where L is a Lewis base. For example, it reacts with pyridine (C 5 H 5 N) to form the pyridine complex: CrCl 3 + 3 C 5 H 5 N → CrCl 3 (C 5 H 5 N) 3. Treatment with trimethylsilylchloride in THF gives the anhydrous THF complex: [14] CrCl 3 ·6H 2 O + 12 (CH 3) 3 SiCl → CrCl 3 (THF) 3 ...

The compound has idealized C 2h symmetry. Each metal centre is pseudo-octahedral. The compound is prepared by the reaction of rhodium trichloride trihydrate and pentamethylcyclopentadiene in hot methanol, from which the product precipitates: [1] 2 C 5 (CH 3) 5 H + 2 RhCl 3 (H 2 O) 3 → [(C 5 (CH 3) 5)RhCl 2] 2 + 2 HCl + 6 H 2 O

Upon contact, H 2 O and HCl combine to form hydronium cations [H 3 O] + and chloride anions Cl − through a reversible chemical reaction: HCl + H 2 O → [H 3 O] + + Cl −. The resulting solution is called hydrochloric acid and is a strong acid.
