Question

write the preparation properties of alkanes alkenes alkynes and Benzene
​

Answer 1

Answer:

The alkanes are saturated hydrocarbons—that is, hydrocarbons that contain only single bonds. Alkenes contain one or more carbon-carbon double bonds. Alkynes contain one or more carbon-carbon triple bonds. Aromatic hydrocarbons contain ring structures with delocalized π electron systems

Benzene can be prepared from aromatic acids through decarboxylation reaction. In this process, sodium salt of the benzoic acid (sodium benzoate) is heated with soda lime to produce benzene along with sodium carbonate.

Answer 2

Answer:

1. The properties of alkynes pretty much follow the same pattern of those of alkanes and alkenes. 2. Alkynes are unsaturated carbon that shares a triple bond at the carbon site 3. All alkynes are odourless and colourless with the exception of ethylene which has a slight distinctive odour. 4. The first three alkynes are gases, and the next eight are liquids. All alkynes higher than these eleven are solids 5. Alkynes are slightly polar in nature 6. The boiling point and melting point of alkyne...
