In an alkane, each carbon atom is sp 3 -hybridized with 4 sigma bonds (either C–C or C–H ), and each hydrogen atom is joined to one of the carbon atoms (in a C–H bond). The longest series of linked carbon atoms in a molecule is known as its carbon skeleton or carbon backbone. The number of carbon atoms may … See more 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 See more 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 … See more 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 … See more 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% methane, 5 ppm ethane), Uranus (1.99% methane, 2.5 ppm ethane) and See more Ordinarily the C-C single bond distance is 1.53 ångströms (1.53×10 m). Saturated hydrocarbons can be linear, branched, or cyclic. … See more The IUPAC nomenclature (systematic way of naming compounds) for alkanes is based on identifying hydrocarbon chains. Unbranched, saturated hydrocarbon chains are named … See more 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 … See more WebDec 10, 2024 · The three simplest alkanes—methane (CH 4 ), ethane (C 2 H 6 ), and propane (C 3 H 8 )—are shown in Figure 1.1 "The Three Simplest Alkanes". The flat representations shown do not accurately portray bond angles or molecular geometry.

Web1. Select the incorrect statement regarding alkanes. a) It is otherwise known as Paraffin b) It is an acyclic saturated hydrocarbon c) In alkanes, C-C bonds are single d) Alkanes have the general formula C n H 2n View Answer 2. Identify the simplest alkane. a) Methane b) Methene c) Ethane d) Ethene View Answer 3. WebHydrocarbons with only single bonds are called alkanes. These are straight chained. If there are one or more double bonds, the class is alkene. If there are one or more triple bonds, the compounds are alkynes.

Alkanes - Crude oil, hydrocarbons and alkanes - BBC Bitesize

WebMay 9, 2024 · It can be easily seen that the only type of covalent bonds present in alkanes are sigma bonds, also loosely known as single bonds. LINE-ANGLE FORMULAS In alkanes of 3 carbon atoms or more, the main carbon chain acquires a zig-zag structure due to the 109.5 o angle between C–C bonds, such as in propane: WebJan 23, 2024 · This equation describes the relationship between the number of hydrogen and carbon atoms in alkanes: H = 2C + 2 where "C" and "H" are used to represent the number of carbon and hydrogen atoms present in one molecule. If C = 2, then H = 6. Many textbooks put this in the following format: CnH2n+2 WebAlkanes are generally viewed as fundamental molecules that do not have functional groups. But when a double or triple bond between carbon atoms is added, or some atom or group of atoms, then functional groups are present. The following molecules each include a functional group (shown in red). cta ct angiography
