Question

Which mixture is given by Dodecane in presence of platinum?

Answer 1

Dodecane $\left({\mathrm{C}}_{12}{\mathrm{H}}_{26}\right)$:

• Dodecane is a $12$-carbon straight-chain alkane.
• It was separated from the essential oils of several different plants, including Zingiber officinale (ginger).
• As a plant metabolite, it serves a purpose.
• N-dodecane is a transparent, colorless liquid.

Pyrolysis:

• Pyrolysis is the term for the heat-induced fragmentation of a chemical in the absence of air.
• It differs from lighting anything on fire.
• It happens when there isn't any air around to prevent chemical oxidation.
• Cracking is the pyrolysis of alkanes.
• The pyrolysis process uses noble metals like platinum and palladium as a catalyst.
• Pentane $\left({\mathrm{C}}_6{\mathrm{H}}_{16}\right)$ and Heptane $\left({\mathrm{C}}_7{\mathrm{H}}_{16}\right)$ are produced as pyrolysis products when dodecane (a component of kerosene oil) is burned at $973\mathrm{K}$ while being catalyzed by palladium, nickel, or platinum.

1. ${\mathrm{C}}_{12}{\mathrm{H}}_{26}\stackrel{\mathrm{Pt}/\mathrm{Pd}/\mathrm{Ni}}{\to }{\mathrm{C}}_7{\mathrm{H}}_{16}+{\mathrm{C}}_5{\mathrm{H}}_{10}+\mathrm{Other}\mathrm{Products}$

Final Answer:

Pentane $\left({\mathrm{C}}_6{\mathrm{H}}_{16}\right)$ and Heptane $\left({\mathrm{C}}_7{\mathrm{H}}_{16}\right)$ is given by Dodecane in presence of platinum
