WebbAlkanes contain carbon-carbon sigma bonds. A sigma bond between two carbon atoms is formed when two sp 3 hybrid orbitals of each carbon overlap along their internuclear axis. The electron distribution of the sigma molecular orbital is symmetrical around the internuclear axis of the C−C bond which is not disturbed due to rotation about its axis. The alkanes range in complexity from the simplest case of methane (CH 4), where n = 1 (sometimes called the parent molecule), to arbitrarily large and complex molecules, like pentacontane (C 50 H 102) or 6-ethyl-2-methyl-5-(1-methylethyl) octane, an isomer of tetradecane (C 14 H 30). Visa mer In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a Visa mer Alkanes with more than three carbon atoms can be arranged in various ways, forming structural isomers. The simplest isomer of an alkane is the one in which the carbon atoms are arranged in a single chain with no branches. This isomer is sometimes called the n-isomer … Visa mer All alkanes are colorless. Alkanes with the lowest molecular weights are gases, those of intermediate molecular weight are liquids, and the heaviest are waxy solids. Table of alkanes Boiling point Alkanes experience … Visa mer Occurrence of alkanes in the Universe Alkanes form a small portion of the atmospheres of the outer gas planets such as Jupiter (0.1% methane, 2 ppm ethane), Saturn (0.2% … Visa mer Ordinarily the C-C single bond distance is 1.53 ångströms (1.53×10 m). Saturated hydrocarbons can be linear, branched, or cyclic. The third group is sometimes called cycloalkanes. … Visa mer The IUPAC nomenclature (systematic way of naming compounds) for alkanes is based on identifying hydrocarbon chains. Unbranched, … Visa mer Alkanes are only weakly reactive with most chemical compounds. The acid dissociation constant (pKa) values of all alkanes are estimated to range from 50 to 70, depending on the … Visa mer
An alkane which can exhibit optical activity is:
WebbPropane and butane are common fuels in propane gas burners and cigarette lighters. Alkanes with 5 to 8 carbons are the major components of gasoline, while diesel contains … WebbThe simplest alkane is methane (CH 4 ), a colorless, odorless gas that is the major component of natural gas. Other simple alkanes are used as fuels and solvents. Physical properties Boiling points The boiling points shown are for the “straight chain” isomers in which there are more than one (Figure 1). cryovac 8189 bag loader
