\[c_{n}h_{2n+2}\] the general formula means that the number of hydrogen atoms. It can be seen how each compound differs from the following by 14 units of molecular. They have a general formula of c n h 2n+2.
Structures and Names of Alkanes
Molecular formula name of straight chain synonyms 1 1 1 ch 4:
Alkenes are often used as a synonym of olefin.
Condensed structural formula of alkane. The name olefin is derived from the greek word olefin gas, which means oil forming. Ch 3 (ch 2) 6 ch 3: Ch 3 ch 2 ch 3:
To name an alkane, first identify the longest chain of carbon atoms in its structure.
Name molecular formula structural formula isomers name molecular formula structural formula isomers; In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings), is an acyclic saturated hydrocarbon. For acyclic alkanes c nh 2n+2 • basically 2h per carbon (2n), plus 2 extra h’s at the ends (+2) • branched isomers for acyclic alkanes still have c nh 2n+2 6. Formula for cyclic alkanes c nh 2n
Each carbon atom creates four bonds, and each hydrogen atom generates a solid bond.
The alkanes comprise a series of compounds that are composed of carbon and hydrogen atoms with single covalent bonds. By saturated hydrocarbons, it means alkanes have single hydrogen and carbon atoms in their chemical formula. Hence, c5h12 is called pentane, c6h14 is called hexane, c7h16 is called heptane and so forth. This group of compounds comprises a homologous series with a general molecular formula of c n h 2 n+2 , where equals any integer.

The chain alkane fits the general formula of c n h 2n+2 (n: Let us learn in detail about alkanes and their physical properties below. Alkanes have the general chemical formula c n h 2n+2. We began our study of organic chemistry in chapter 4 covalent bonding and simple molecular compounds with the hydrocarbons the simplest organic compound, composed of carbon and hydrogen atoms only.
Iupac nomenclature of alkanes, alkynes, and alkenes are explained below:
Condensed structural formula for an alkane.! The first part of the name refers to the number of carbon atoms its molecule contains; The condensed structural formulas of the first ten straight chain alkanes and their iupac names are listed below: Same formula, but the atoms are bonded together in a different order 2.
Other ways of representing organic compounds.
C n h 2 n + 2. Alkanes are the simplest hydrocarbons known to us. C n h 2n+2 each homologous series has its own general formula. The straight chain alkanes share the same general formula:
To use the general formula, replace n in the general formula with the number of c (carbon) atoms.
What is the name of an alkane having 6 carbon atoms and 14 hydrogen atoms? The general formula of alkenes is c n h 2n. Alkenes are unsaturated hydrocarbons having a double bond between the carbon atoms. Alkanes belong to the family of saturated hydrocarbons that is;
8 ), butane (c 4 h.
Methane (ch 4 ), ethane (c 2 h. Names start in “cyclo” (cyclopentane, cyclooctane, etc.) 7. The formula for alkanes is cnh2n+2. 6 ), propane (c 3 h.
The simplest alkane, methane, has one carbon atom and a molecular formula of ch 4.
They comprise only hydrogen and carbon. Again by way of example, consider the series of alkanes: 10 rows the principle of homology allows us to write a general formula for alkanes: They can be categorized into three groups which are:
Positive integer), and the number of h atoms reaches the maximum level in chain alkanes.
