Which hydrocarbon is an unsaturated hydrocarbon?
alkenes
The unsaturated hydrocarbons are the alkenes with one double bond and the alkynes with one triple bond. There are other straight-chain hydrocarbons that are unsaturated containing more than one multiple bond, some with more than one double bond, and some with a mixture of double bonds and triple bonds.
Which are unsaturated ring hydrocarbons?
An unsaturated hydrocarbon is a type of hydrocarbon which has at least one double bond, triple bond, or ring in its carbon chain. These molecules will therefore have fewer hydrogen atoms than the maximum the carbon chain could possibly hold (if all bonds were single bonds).
What classes of hydrocarbons are unsaturated?
Unsaturated hydrocarbons, based on the types of bonds they contain, can be classified into alkenes, alkynes, and aromatic hydrocarbons.
Which structure represents an unsaturated hydrocarbon?
Answer: Alkenes have the general formula CnH2n, and are examples of unsaturated hydrocarbons. The presence of a double bond compound’s structure causes there to be two fewer hydrogen atoms in the molecule than there are in an alkane with the same number of carbon atoms.
Are benzene rings unsaturated?
Aromatic hydrocarbons are a special class of unsaturated hydrocarbon based on a six carbon ring moiety called benzene. The saturated hydrocarbon cyclohexane is transformed into the aromatic hydrocarbon benzene by adding three alternating carbon–carbon double bonds, as shown in Fig.
Why is ethene classified as an unsaturated hydrocarbon?
Ethylene has a double bond between the carbons so it is classified as unsaturated hydrocarbon. It’s the simplest alkene with the IUPAC name ethene.
What is CH3CH2CH2CHO classified as?
The organic compound represented by the condensed structural formula CH3CH2CH2CHO is classified as an. A) Aldehyde.
Is methyl an unsaturated hydrocarbon?
Now place the methyl group on the third carbon atom and add enough hydrogen atoms to give each carbon atom a total of four bonds….25.4: Unsaturated Hydrocarbons.

| Boiling Point (°C) | 30 |
Are all aromatic hydrocarbons unsaturated?
Aromatic hydrocarbons appear to be unsaturated, but they have a special type of bonding and do not undergo addition reactions.
Is ethene an unsaturated hydrocarbon?
Ethylene has a double bond between the carbons so it is classified as unsaturated hydrocarbon. It’s the simplest alkene with the IUPAC name ethene. It is the most produced in the world.
What makes an aromatic hydrocarbon an unsaturated hydrocarbon?
Aromatic hydrocarbons, also known as arenes, are unsaturated hydrocarbons that contain the benzene ring, or aromatic ring, in their chemical structure. The benzene ring is a hexagon with alternating double bonds between carbon atoms – so it has three double bonds within the ring.
How are aromatic hydrocarbons defined in figure 8.2?
Aromatic hydrocarbons are defined by having 6-membered ring structures with alternating double bonds (Fig 8.2). Figure 8.2: Aromatic Hydrocarbons. Aromatic hydrocarbons contain the 6-membered benzene ring structure (A) that is characterized by alternating double bonds.
Why are aromatic rings considered to be unsaturated alkenes?
Thus, they have formulas that can be drawn as cyclic alkenes, making them unsaturated. However, due to the cyclic structure, the properties of aromatic rings are generally quite different, and they do not behave as typical alkenes.
Which is the chemical formula for a saturated hydrocarbon?
A saturated hydrocarbon, also known as an alkane, is a hydrocarbon in which all bonds between the carbon atoms are single bonds. The general chemical formula for an alkane is CnH2n+2. Alkanes in which the carbon atoms form long chains are called straight-chain alkanes.
