∙ 7y agoAlkynes undergo many addition reactions such as: catalytic hydrogenation, addition by electrophilic reagents, hydration with tautomerism, hydroboration reactions, and oxidations. They also undergo nucleophilic addition reactions & reduction. Finally alkynes are the strongest bronsted acids made from only hydrocarbons.
Formaldehye is H2C=O and has a double bond. The Carbon-oxygen bond is slightly polar and the carbon has partial positive charge and oxygen slightly negative charge. Hence formaldehyde will undergo nucleophilic addition addition reaction across the C=O.
When alkenes undergo addition reactions, they typically form a new single bond, resulting in a saturated compound. This is because the double bond in the alkene is broken, allowing the addition of atoms or groups to each carbon of the original double bond.
Both ethane and ethene can undergo combustion reactions to produce carbon dioxide and water. They can also undergo halogenation reactions with halogens such as chlorine or bromine to form halogenated hydrocarbons. Additionally, they can undergo polymerization reactions to form longer chain hydrocarbons or polymers.
Bromine water can be used to test for an alkene by adding it to the alkene. The alkene will decolorize the orange-brown bromine water, turning it colorless, due to the addition of bromine across the carbon-carbon double bond in the alkene molecule. This reaction tests for the presence of unsaturation in the compound.

Saturated hydrocarbons undergo addition reactions, where new atoms are added to the carbon-carbon bonds. Unsaturated hydrocarbons undergo substitution or elimination reactions, where atoms are substituted for the hydrogens on the carbon-carbon double or triple bond or double bond is eliminated to form a single bond, respectively.
Propane does not typically undergo addition reactions due to its stable structure as a saturated hydrocarbon. It is not reactive under normal conditions and tends to undergo combustion or substitution reactions rather than addition reactions.

Unsaturated hydrocarbons, such as alkenes and alkynes, undergo addition reactions where the double or triple bond is broken and new atoms or groups are added to the carbon atoms. This can involve hydrogenation to form saturated hydrocarbons, halogenation to add halogen atoms, or hydration to add a hydroxyl group. Additionally, unsaturated hydrocarbons can undergo polymerization reactions to form long chains of repeating units.
Combustion of saturated hydrocarbons produces only carbon dioxide and water, while combustion of unsaturated hydrocarbons can produce carbon monoxide, carbon dioxide, water, and soot due to incomplete combustion. Unsaturated hydrocarbons may also produce more heat during combustion compared to saturated hydrocarbons.
Benzene undergo substitution reaction rather than addition?
An alkene will not undergo a substitution reaction, where an atom or group replaces another atom or group in a molecule. Alkenes typically undergo addition reactions, where new atoms or groups are added to the carbon-carbon double bond.
When hydrocarbons react with oxygen, they undergo combustion to produce carbon dioxide (CO2) and water vapor (H2O) as the main products. This chemical reaction releases energy in the form of heat and light.
No, hydrochloric acid (HCl) typically does not react with alkanes. This is because alkanes are non-reactive hydrocarbons and do not readily undergo reaction with acids like HCl.
When alkenes undergo addition reactions, they typically form a new single bond, resulting in a saturated compound. This is because the double bond in the alkene is broken, allowing the addition of atoms or groups to each carbon of the original double bond.
