How many CC and CH bonds are in propane respectively?
The chemical formula of propane is C3H8. Propane has single bonds between the carbon atoms (C-C-C) and 3 hydrogen atoms attached to the terminal carbons while only 2 hydrogen atoms are attached to the central atom by a single bond. This accounts for 2 C-C bonds and 8 C-H bonds resulting in a ratio of 1:4.
Why is propane an alkane?
Hydrocarbons which contain only single bonds are called alkanes. They are called saturated hydrocarbons because there is a hydrogen in every possible location. This gives them a general formula CnH2n+2. The first four alkanes are methane, ethane, propane, and butane with the Lewis symbols shown below.
What is the functional group of propane?
| Name | Example |
|---|---|
| Alkane | CH3CH2CH3 (propane) |
| Alkene | CH3CH=CH2 (propene) |
| Alkyne | CH3C CH (propyne) |
| Alkyl halide | CH3Br (methyl bromide) |
Is propane an alkene?
Alkane is the simplest hydrocarbon with only C-C single bonds. The chain alkane fits the general formula of CnH2n+2 (n: positive integer), and the number of H atoms reaches the maximum level in chain alkanes….2.1 Structures of Alkenes.
