3) 2 (C 2 H 5). Isopentane is a volatile and flammable liquid. It is one of three structural isomers with the molecular formula C 5 H 12, the others being pentane (n-pentane) and neopentane (2,2-dimethylpropane). Isopentane is commonly used in conjunction with liquid nitrogen to achieve a liquid bath temperature of −160 °C.
2-Methylpentane, trivially known as isohexane, is a branched-chain alkane with the molecular formula C 6 H 14.It is a structural isomer of hexane composed of a methyl group bonded to the second carbon atom in a pentane chain.
The nitratoxycarbon functional group itself—a carbon atom and a nitrogen atom linked by three oxygen-atom bridges—has yet to be observed in any chemical compound. Computational chemistry studies indicate that it is only metastable , with other structural isomers such as the carboxylic nitroso - ester (C(=O)ONO) being more stable. [ 3 ]
Calculations indicate that tri-tert-butylamine should be planar at nitrogen. Though arguably a more hindered molecule, the structurally analogous tri-tert-alkyl carbinol 2,2,4,4-tetramethyl-3-t-butyl-pentane-3-ol (tri-tert-butylcarbinol, t Bu 3 COH), has been known for decades (prepared by Bartlett and coworkers in 1945).
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula −C n H 2n−1. [2] Typically an alkyl is a part of a larger molecule. In structural formulae , the symbol R is used to designate a generic (unspecified) alkyl group.
