A non cyclic alkane always has a number of hydrogen atoms equal to 2c + 2, where c is the number of carbon atoms. Therefore, hexadecane, an alkane with 16 carbon atoms, will have 34 hydrogen atoms.
Dodecane has 24 hydrogen atoms. The general formula for an alkane is CnH2n+2, where n is the number of carbon atoms. Dodecane has 12 carbon atoms, so it will have 2(12) + 2 = 24 hydrogen atoms.
Decane has 10 carbon atoms and 22 hydrogen atoms.
AnswerAlkenes have the general formula CnH2n. Cyclic alkenes have the general formula CnH2n-2 as do alkynes.Or you can say that for every carbon there are 2 hydrogens. 2n
Carbon atom A can form up to four covalent bonds with hydrogen atoms, so it can have a maximum of four hydrogen atoms attached to it.
Since the chemical formula for Cycohexane is C6H12, it has 12 atoms of Hydrogen.
An alkane with six carbon atoms would be hexane (C6H14). Since each carbon atom is bonded to two hydrogen atoms in an alkane, you would have 6 carbon atoms x 2 hydrogen atoms per carbon = 12 hydrogen atoms.
In a noncyclical alkane with five carbon atoms, each carbon atom is bonded to 2 hydrogen atoms, except the terminal carbon atoms which are bonded to 3 hydrogen atoms. Therefore, in a 5-carbon noncyclical alkane, there would be a total of 12 hydrogen atoms.
The generic formula for an alkane is CnH(2n + 2).Therefore, an alkane with 3 carbon atoms would have 8 hydrogen atoms.
In an alkane the number of hydrogen atoms is two greater than twice the number of carbon atoms. If we reverse this rule, we find that the number of carbon atoms is one less than half the number of hydrogen atoms. 32/2=16 16-1=15 So our alkane would have 15 carbon atoms. This alkane would be pentadecane or one of its isomers.
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.
In an alkane molecule with ten carbon atoms, the general formula is C10H22. Each carbon atom forms four bonds, leaving 22 hydrogen atoms to satisfy the valency requirement of carbon. So, there are 22 hydrogen atoms in an alkane molecule with ten carbon atoms.
Then the acyclic alkane hydrocarbon contains 2n+2 hydrogen atoms.
An acyclic alkane with 13 carbon atoms will have 28 hydrogen atoms. This is because each carbon atom in an alkane forms 4 single bonds with other atoms, and in this case, each of the 13 carbon atoms will form single bonds with 2 hydrogen atoms and 2 other carbon atoms.
Formula for alkanes:Number of H = 2 * number of C + 2So, using this formula, H = 2 * 10 + 2, which gives 22
Dodecane has 24 hydrogen atoms. The general formula for an alkane is CnH2n+2, where n is the number of carbon atoms. Dodecane has 12 carbon atoms, so it will have 2(12) + 2 = 24 hydrogen atoms.
A propyl group consists of 3 carbon atoms, so 3 propyl groups would have 9 carbon atoms. Each carbon atom is bonded to 3 hydrogen atoms in an alkane, so 3 propylheptane would have 27 hydrogen atoms in total.
In an alkane, each carbon atom forms four covalent bonds with other atoms. This means that each carbon atom in an alkane molecule is bonded to two other carbon atoms and two hydrogen atoms, resulting in a total of four covalent bonds per carbon atom.
