What are the chemical properties of alkenes?

What are the chemical properties of alkenes?

Unsaturated alkenes compounds are highly reactive. They form a double bond between carbon-carbon atoms which makes them less stable due to loosely held pi bonds. Alkene group reacts with halogens such as bromine, chlorine except for iodine as it’s an exception and it does not react in normal conditions.

What are the chemical properties of alkynes?

All alkynes are odourless and colourless with the exception of ethylene which has a slight distinctive odour. Also, the boiling points of alkynes are slightly higher than those of their corresponding alkenes, due to the one extra bond at the carbon site.

What is an alkene functional group?

The functional group in an alkene is a carbon-carbon double bond. The functional group in an alkyne is a carbon-carbon triple bond. Aromatics are cyclic strcutures that are planar, fully conjugated and that possess an odd number of electron pairs in the π bonding system.

What are the chemical properties of benzene?

Properties of Benzene

  • Benzene is immiscible in water but soluble in organic solvents.
  • It is a colourless liquid and has an aromatic odour.
  • It has a density of 0.87g cm-3.
  • Benzene has a moderate boiling point and a high melting point.
  • Benzene shows resonance.
  • It is highly inflammable and burns with a sooty flame.

What are properties of hydrogen?

Hydrogen is a colorless, odorless, tasteless, and nonpoisonous gas under normal conditions on Earth. It typically exists as a diatomic molecule, meaning each molecule has two atoms of hydrogen; this is why pure hydrogen is commonly expressed as “H2“.

What are the chemical properties of alcohols?

What are the Properties of Alcohols? Alcohols are organic compounds in which a hydrogen atom of an aliphatic carbon is replaced with a hydroxyl group. Thus an alcohol molecule consists of two parts; one containing the alkyl group and the other containing functional group hydroxyl group. They have a sweet odour.

What is an example of an alkane?

Alkanes are saturated hydrocarbon consist of carbon and hydrogen only without any functional group. The general formula of alkane is C nH 2n+2. Example: methane (CH 4), ethane (C 2H 6), propane (C 3H 8) etc.

Is CH3 an alkane?

It’s butane, an alkane, because the ratio of Carbon to Hydrogen atoms is Cn -H2n+2. CH3-CH2-CH2-CH3 has a molecular formula of C4H10. An alkene’s C/H ration is Cn – H2n and an alkyne, Cn – H 2n-2. So butene would have the molecular formula C4H8 and butyne, C4H6.

What is the name of an alkane?

In organic chemistry, an alkane, or paraffin (a historical name that also has other meanings), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single. Alkanes have the general chemical formula C nH 2n+2.

What is an alkane series?

alkane series – a series of non-aromatic saturated hydrocarbons with the general formula CnH(2n+2) alkane, methane series, paraffin series, paraffin . aliphatic compound – organic compound that is an alkane or alkene or alkyne or their derivative.
