carboxylic salt of sodium. Give steps of

reaction​

Answer 1

Answer:

Preparation of Alkanes – Alkanes are referred to as the saturated hydrocarbons, that is, hydrocarbons having all carbon atoms bonded to other carbon atoms or hydrogen atoms with sigma bonds only. As the alkanes possess weak Van Der Waals forces, the first four members, C1 to C4 are gases, C5 to C17 are liquids and those containing 18 carbon atoms or more are solids at 298 K. They are colourless and odourless. They are prepared in laboratories and industries through various techniques. Some techniques for the preparation of alkanes are:

Preparation of Alkanes from unsaturated hydrocarbon:

Alkane can be prepared from alkene and alkyne through the process of hydrogenation. In this process, dihydrogen gas is added to alkynes and alkenes in the present catalyst. This catalysts which are finely divided is like nickel, palladium or platinum to form alkanes. With the help of nickel as the catalyst, this reaction takes place at an elevated temperature, whereas the reaction takes place at room temperature with platinum as the catalyst.
