Pentyl is a five-carbon alkyl group or substituent with chemical formula-C 5 H 11. It is the substituent form of the alkane pentane . In older literature, the common non-systematic name amyl was often used for the pentyl group.
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 ...

Alkyls include methyl, (−CH 3), ethyl (−C 2 H 5), propyl (−C 3 H 7), butyl (−C 4 H 9), pentyl (−C 5 H 11), and so on. Alkyl groups that contain one ring have the formula −C n H 2n−1, e.g. cyclopropyl and cyclohexyl. The formula of alkyl radicals are the same as alkyl groups, except the free valence "−" is replaced by the dot ...
5 H 12 or CH(CH 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.
It is one of the three structural isomers with the molecular formula C 5 H 12 , the other two being n-pentane and isopentane. Out of these three, it is the only one to be a gas at standard conditions; the others are liquids. It was first synthesized by Russian chemist Mikhail Lvov in 1870. [4]
Pentenes are alkenes with the chemical formula C 5 H 10.Each molecule contains one double bond within its molecular structure. Six different compounds are in this class, differing from each other by whether the carbon atoms are attached linearly or in a branched structure and whether the double bond has a cis or trans form.
The molecular formula C 5 H 12 (molar mass: 72.15 g/mol, exact mass: 72.0939 u) may refer to: Pentanes. Pentane; Eupione, or eupion; Isopentane, or methylbutane;
