For a straight-chain alkane, this would be C10H22 - decane. However, if this is a cyclic alkane, you would have C10H20 (cyclodecane). There are also numerous options for a branching alkane with various names and carbon to hydrogen ratios.
The general formula of linear alkanes is CnH2n+2. If an alkane with 125 carbons exist (I don't know) the chemical formula will be C125H252 and the name pentacosehectane.
The chemical formula for an alkane with 42 carbons is C42H86. It follows the general formula CnH2n+2, where n represents the number of carbon atoms in the alkane chain.
The formula for an alkane with four carbon atoms is C₄H₁₀. This alkane is named butane.
The methyl and ethyl groups, respectively.
The generic formula for a non cyclic alkane is CxH(2x + 2).
C15h32
The general formula of linear alkanes is CnH2n+2. If an alkane with 125 carbons exist (I don't know) the chemical formula will be C125H252 and the name pentacosehectane.
The molecular formula for an alkane with 18 carbon atoms is C18H38. Alkanes have the general formula CnH2n+2, where n is the number of carbon atoms.
The chemical formula for an alkane with 42 carbons is C42H86. It follows the general formula CnH2n+2, where n represents the number of carbon atoms in the alkane chain.
A decane molecule has 10 carbon atoms. Decane is an alkane with the chemical formula C10H22.
The formula for an alkane with four carbon atoms is C₄H₁₀. This alkane is named butane.
A 4 carbon linear alkane, such as butane, has the chemical formula C4H10 because each carbon atom in the chain can form bonds with 3 hydrogen atoms. In contrast, a 4 carbon cyclic alkane, such as cyclobutane, has the chemical formula C4H8 because two of the carbon atoms in the ring are involved in forming the ring structure and cannot form bonds with additional hydrogen atoms.
The methyl and ethyl groups, respectively.
The generic formula for a non cyclic alkane is CxH(2x + 2).
Formula for alkanes:Number of H = 2 * number of C + 2So, using this formula, H = 2 * 10 + 2, which gives 22
In an alkane, each carbon atom is bonded to 4 hydrogen atoms. So, the number of hydrogens in an alkane can be determined by the formula 2n+2, where n is the number of carbon atoms in the alkane.
The generic formula for an alkane is CnH(2n + 2).Therefore, an alkane with 3 carbon atoms would have 8 hydrogen atoms.
