To prepare 1-hexyne from ethyne, you would first need to convert ethyne to 1-bromohexane through a series of reactions. Ethyne would undergo bromination to form 1,2-dibromoethane, followed by a substitution reaction with sodium cyanide to form 1-cyano-1,2-dibromoethane. Finally, hydrolysis of the nitrile group would yield 1-hexyne. This multi-step process allows for the conversion of ethyne to 1-hexyne through intermediate compounds.
To prepare 10-hexyne from ethyne, you can first convert ethyne to 1-bromopentane using HBr and peroxides. Then, treat 1-bromopentane with NaNH2 to form the triple bond at the desired terminal carbon, resulting in the formation of 10-hexyne.
1. Explain with suitable examples: a) Both chlorobenzene and chloroethene do not undergo substitution reactions under ordinary conditions with NaOH. b) Carbonyl group of benzaldehyde is less reactive towards nucleophilic addition reactions than the carbonyl group of ethanal. 2. Write the product (s) and mechanism for the following reactions: (5) 3. How would you carry out following conversions? a) Ethene to oxirane b) Benzyl magnesium chloride to 3-phenylpropanol c) Propene to glycerol d) Benzaldehyde to 3-phenylpropenoic acid e) Ethanol to trichloromethane (5) 4. a) How would you differentiate between different classes of alcohols? b) Give two reduction methods which can convert a carbonyl compound to an alkane.
The isomers of 1-hexyne are cis-2-hexene, trans-2-hexene, and 3-hexyne. These isomers have different chemical structures due to the positioning of the carbon-carbon triple bond within the hexane chain.

No, 1-hexyne is not an isotope. Isotopes are same elements that have the same number of protons (and therefore the same chemical properties) but different numbers of neutrons. They have slightly different atomic masses due to the varying number of neutrons in their nuclei. 1-hexyne, on the other hand, is a specific chemical compound. It is an alkyne with the molecular formula C6H10 and a carbon-carbon triple bond at the first position in a hexane chain. Isotopes are not specific chemical compounds, but they are variations of elements.
No, hexyne does not react with sulfur dioxide to form benzene and oxygen. The reaction between hexyne and sulfur dioxide does not lead to the formation of benzene or oxygen.

By combustion ethyne is transformed in carbon dioxide and water.
Oxygen is much more dense than ethyne. This is why a test tube full of ethyne would be held upside down so the ethyne doesnt escape into the air.
