What hydrocarbon is formed when two carbon atoms are joined by a double bond?
Alkene
The correct answer is Alkene. A hydrocarbon in which two carbon atoms are joined by a double bond is called an Alkene. A hydrocarbon is an organic compound consisting entirely of hydrogen and carbon.
Which type of hydrocarbon contains at least one double covalent bond?
Alkenes
Alkenes are unsaturated hydrocarbons with at least one double bond between carbon atoms.
Which hydrocarbon has a double bond in the molecule?
alkenes
Unsaturated hydrocarbon molecules that contain one or more double bonds are called alkenes.
Which is the smallest hydrocarbon?
Methane
Methane (CH₄), the smallest hydrocarbon, is an uncolored and non-smelling gas. It has a symmetrical non-polar structure, where the carbon atom is surrounded by four hydrogen atoms in a perfectly tetrahedral arrangement.
When two carbon atoms are joined by a double bond the carbons and atoms bound to them form which of the following structures?
When two carbon atoms are joined together by two bonding pairs of electrons, a double bond is formed. A double bond forces the two carbon atoms and attached groups into a rigid, planar structure. As a result, a molecule such as CHCl=CHCl can exist in two nonidentical forms called geometric isomers.
What is the hydrocarbon formula?
The general formula for a saturated hydrocarbon containing one ring is CnH2n. For most compounds, information beyond the chemical formula will be needed to elucidate their structure….Answer.

What is a carbon double bond?
A carbon–carbon bond is a covalent bond between two carbon atoms. A double bond is formed with an sp2-hybridized orbital and a p-orbital that is not involved in the hybridization. A triple bond is formed with an sp-hybridized orbital and two p-orbitals from each atom.
Which of the following molecules has a carbon to carbon double bond?
Alkenes are hydrocarbons which contain carbon-carbon double bonds. Their general formula is CnH2n for molecules with one double bond (and no rings). Alkenes are also known as olefins, after the original name for ethene, olefiant gas.
What is the smallest alkene?
Ethene is the smallest of the alkene series. More commonly called ethylene, it is an important intermediate in many chemical synthesis processes.
A double bond is formed when two atoms use two electron pairs to form two covalent bonds; a triple bond results when two atoms share three electron pairs to form three covalent bonds.
When two carbon atoms are joined by a double bond how many electron pairs are shared between two carbons?
Carbon can form single, double, or even triple bonds with other carbon atoms. In a single bond, two carbon atoms share one pair of electrons. In a double bond, they share two pairs of electrons, and in a triple bond they share three pairs of electrons.
How do you find the double bond of a hydrocarbon?
H-C-ŒC-C-H 2. DPAWINC I-IYDPOCAPOONS When drawing the structural formulas of hydrocarbons, you just follow the name of the hydrocarbon — the prefix will tell you how many carbons & the ending will tell you if you need a double or triple bond. For now, do not worry where you put the double/triple bond.
How many bonds can a carbon atom form with other atoms?
Carbon (Figure 4.2) has four valence electrons which means that each carbon atom can form a maximum of four bonds with other atoms. Because of the number of bonds that carbon can form with other atoms, organic compounds can be very complex. Carbon can form bonds with other carbon atoms to form single, double or triple covalent bonds.
What are the bond angles about the carbon-carbon double bond?
All bond angles about the carbon-carbon double bond are 120o. All atoms bonded to the double bonded carbon atoms lie in the same plane. Carbon-carbon triple bond angles are 180o.
What are the functional groups of hydrocarbons?
In one group of organic compounds, called the hydrocarbons, the single, double and triple bonds between carbon atoms give rise to the alkanes, alkenes and alkynes, respectively. The double carbon-carbon bonds (in the alkenes) and triple carbon-carbon bonds (in the alkynes) are examples of functional groups.
