ethyne to propanone

To convert the given compounds using various reactions, here are the steps for each conversion:

(a) Ethane to Propanone:
- Use oxidation reaction to convert ethane to ethanol using an oxidizing agent like acidified potassium dichromate (K2Cr2O7) or acidified potassium permanganate (KMnO4)
- Further oxidize ethanol to propanone using the same oxidizing agent.

(b) Propanone to Ethane:
- Use reduction reaction to convert propanone to propanol using a reducing agent like lithium aluminum hydride (LiAlH4) or sodium borohydride (NaBH4)
- Then, dehydrate propanol to produce ethene using a dehydrating agent like concentrated sulfuric acid (H2SO4) or phosphoric acid (H3PO4)
- Convert ethene to ethane using a hydrogenation reaction, which can be achieved using a catalyst such as platinum (Pt), palladium (Pd), or nickel (Ni).

(c) Isobutane to Propanone:
- Use oxidation reaction to convert isobutane to isobutanol using an oxidizing agent like acidified potassium dichromate (K2Cr2O7) or acidified potassium permanganate (KMnO4)
- Further oxidize isobutanol to propanone using the same oxidizing agent.

(d) Methane to Benzene:
- This conversion involves a multistep process known as the Wurtz reaction. Firstly, convert methane to chloromethane by halogenation using chlorine (Cl2) or bromine (Br2) with ultraviolet (UV) light as a catalyst.
- Convert chloromethane to ethane using a Wurtz reaction with sodium (Na) or potassium (K) metal as a reducing agent.
- Combine and eliminate one molecule of ethane using pyrolysis at high temperature and pressure to produce benzene.

(e) Benzene to Methane:
- This conversion cannot be directly achieved using the mentioned reactions. It requires specialized processes like steam reforming, gasification, or Fischer-Tropsch synthesis, which are beyond the scope of this explanation.

(f) Ethyne to Methane:
- Use hydrogenation reaction to convert ethyne to ethene. This can be achieved using a catalyst like platinum (Pt), palladium (Pd), or nickel (Ni).
- Then, convert ethene to ethane using a hydrogenation reaction with the same catalyst.

(g) Propanone to Benzene:
- This conversion is not possible using the mentioned reactions. Benzene cannot be directly obtained from propanone using oxidation, reduction, or halogenation reactions. Specialized methods such as the Friedel-Crafts reaction or aromatic hydrocarbon synthesis are required.

(h) Ethene to Propene:
- This conversion involves an isomerization reaction. It can be achieved using a catalyst like phosphoric acid (H3PO4) or a zeolite catalyst.

(i) Propan-2-ol to Propan-1-ol:
- Use dehydration reaction to convert propan-2-ol (isopropanol) to propene. This can be achieved using a dehydrating agent like concentrated sulfuric acid (H2SO4) or phosphoric acid (H3PO4).
- Then, add water to propene in the presence of an acid catalyst like sulfuric acid (H2SO4) or phosphoric acid (H3PO4) to convert it to propan-1-ol.
