1.The first four (i.e. c1 to c4) members of alkanes are gases,c5 to c17 are all colourless liquids, and higher than c17 are all colourless solids .
2. They are insoluble in water but soluble in organic compounds.
3. They are lighter than water (less dense) and float on it.
4. They are bad conductors of heat and electricity.

What is the difference in acidity between alkynes, alkenes, and alkanes?
Alkynes are more acidic than alkenes and alkanes. Alkenes are more acidic than alkanes.
What are the key differences between an alkane, alkene, and alkyne in terms of their chemical structures and reactivity?
Alkanes are saturated hydrocarbons with single bonds, alkene have double bonds, and alkynes have triple bonds. Alkanes are the least reactive, while alkenes and alkynes are more reactive due to the presence of double and triple bonds, respectively. Alkenes can undergo addition reactions, while alkynes can undergo both addition and elimination reactions.
How can bromine water test the difference between alkanes and alkenes?
Bromine water can differentiate between alkanes and alkenes because alkenes can decolourize bromine water due to their ability to undergo addition reactions. Alkanes, being saturated hydrocarbons, do not react with bromine water because they lack double bonds to facilitate the addition reaction.
What is the structure of alkanes alkenes alkynes?
A line structural formula of alkanes would have single lines, which represent single bonds, between the symbols of the carbon and hydrogen atoms, and would show the arrangement of the atoms in a molecule of the alkane. Refer to the related links for illustrations of the first two alkanes, methane, CH4, and ethane, C2H6.
Why does the bromine dissolved in carbon tetrachloride is not used to differentiate between alkenes and alyles?
Bromine dissolved in carbon tetrachloride is not typically used to differentiate between alkenes and alkynes because both alkenes and alkynes react with bromine under mild conditions, leading to addition reactions and forming dibromo compounds. This reaction does not provide a clear distinction between the two types of compounds. Other reagents, such as potassium permanganate or ozone, are more commonly used for distinguishing between alkenes and alkynes based on their respective chemical reactivity.

What is the difference between the carbon groups called alkanes and alkenes?
Alkenes have at least one double bond between two carbon atoms; alkanes don't.

What is the classification test of hydrocarbons?
1)Bromine solution in carbontetrachloride is used to identify alkanes, alkenes and alkynes. alkanes don't react therefore the color remains as it is ie, brown while alkenes and alkynes react and therfore brown color disappears. 2)Ammoniacal cuprous chloride when reacted with alkanes alkenes give no precipitate while with alkynes give red precipitate. Thus, alkanes with no reaction and unsaturation can be identified from the first test while alkynes from second test. combustion test solubility test kmno4 test sulfuric acid test

What is alkanes and alkenes?
The difference between an alkane and an alkene is that: Alkanes have only single bonds between carbon atoms and are said to be saturated: when put in bromine water, the bromine water stays orange - formula: CnH2n+2; Alkenes: have one or more double bond(s) between carbon atoms and are unsaturated: when put in bromine water, the bromine water turns clear - formula: CnH2n.
What accounts for the differences between alkynes alkenes and alkanes?
Alkane: -ane. C-C interaction has single bond Alkene: -ene. C-C interaction has double bond Alkyne: -yne. C-C interaction has triple bond Least reactive alkanes are saturated hydrocarbons, while alkene and alkyne not. Alkanes undergo susbstitution reaction while others under go addition reactions rather. Alkanes rule is CnH2n+2 while alkene CnH2n and alkyne CnH2n-2.

Alkenes are unsaturated why?
Alkenes are considered unsaturated because of the presence of a double bond between two or more carbons. A hydrocarbon is only saturated when there are only single bonded carbons present (Alkanes).
What are the three main groups of hydrocarbons?
Anything ending with "...ane" (methane), "...ene" (benzene), "...yne" (ethyne), "...ol" (propanol), "...oic acid" (ethanoic acid). There are more, as there are tens of thousands of hydrocarbons.
What are alkanes?
Answer Alkanes are saturated hydrocarbons having a general formula CnH2n+2. Alkanes are unreactive comparing to alkenes, they are not affected by acids or alkalies. But they burn well in a good supply of oxygen, forming carbon dioxide and water vapour. giving out plenty of heat.
