What is the molecular formula for a 13 carbon alkane?
4.2 Alkanes
| Number of Carbon Atoms | Name | Molecular Formula |
|---|---|---|
| 11 | Undecane | C11H24 |
| 12 | Dodecane | C12H26 |
| 13 | Tridecane | C13H28 |
| 14 | Tetradecane | C14H30 |
Which formula represents an alkane with 12 carbon atoms?
dodecane
Determine the formula for dodecane, an alkane with twelve carbons. The general formula will be C nH 2 n + 2. It has twelve carbons, so n = 12. The number of hydrogens is 2n+2 = 2(12)+2 = 26.
What is the molecular formula of an alkane with 10 carbon atoms?
Decane
The general formula for the alkanes is C nH 2n+2 (where n is the number of carbon atoms in the molecule). Decane is an alkane. Its molecules contain 10 carbon atoms .
What is an alkane with 11 carbons called?
undecane (11 carbons) dodecane (12 carbons) tridecane (13 carbons)
How do you calculate an alkane?
Alkynes have one or more carbon-carbon triple bonds. Alkenes and alkynes are called as unsaturated hydrocarbons. Alkanes have the general formula of CnH2n+2 where n is the number of carbon atoms.
How do you find the molecular formula of alkanes?
The principle of homology allows us to write a general formula for alkanes: CnH2n + 2. Using this formula, we can write a molecular formula for any alkane with a given number of carbon atoms. For example, an alkane with eight carbon atoms has the molecular formula C8H(2 × 8) + 2 = C8H18.
What is alkyne formula?
Alkynes are hydrocarbons which contain carbon-carbon triple bonds. Their general formula is CnH2n-2 for molecules with one triple bond (and no rings).
What is the formula of an alkane containing 18 hydrogen atoms?
Straight-Chain and Branched Alkanes
| Table 1. Summary of the Straight-Chain Alkanes | ||
|---|---|---|
| Name | Formula | Number of Structural Isomers |
| Octadecane | C18H38 | |
| Nonadecane | C19H40 | |
| Eicosane | C20H42 | 366,319 (!) |
What is molecular formula of alkane?
Alkanes are organic compounds composed of single-bonded carbon and hydrogen atoms. The formula for alkanes is CnH2n+2. They can be categorized into three groups which are: chain alkanes, cycloalkanes, and branched alkanes. The most basic family of compounds has been called alkanes.
How do you find the molecular formula of an alkane?
Which is the correct formula for alkane hydrocarbons?
Alkane:- Aliphatic saturated hydrocarbons in which carbon atoms are attached with each other by means of single covalent bond are called as alkanes. Their general molecular formula, CnH2n+2. where n= number of carbon atoms.
What is the formula for methane long chain alkane?
The simple alkane methane contains one carbon atom and CH 4 as its molecular formula. As this compound have just single covalent bonds only, therefore, its structural formula is In a long chain alkane molecule, additional carbon atoms are attached to each other with the help of a single covalent bond.
What is the formula for alkene and alkyne?
Answer Wiki. General formula for Alkane is CnH(2n+2) ; n is integer, n= 1, 2, 3…. For alkyne it is CnH(2n-2) ; n = 2,3,4… Since, alkene and alkynes refers to double bonded carbons & tripple bonded carbons respectively, there must be at least 2 carbon atoms.
Why are alkanes called the simplest family of compounds?
The simplest family of compounds are called alkanes. They contain only carbon and hydrogen. Each carbon atom forms four bonds and each hydrogen atom forms one bond. Chemists use line-angle formulas because they are easier and faster to draw than condensed structural formulas.
