Question

C6 h14 reacts with cr2o3 at 770 Kelvin gives what​

Answer 1

Answer:

Explanation:

Alkanes Containing 6 to 10 Carbon Atoms Are Converted Into Benzene And It's Homologous At High Temperature And In Presence Of a Catalyst.

For Example, When n-Hexane Is Passed Over Chromium Oxide (Cr2O3) Supported Over Alumina (Al2O3) at 600 degree Celsius, Benzene Is Produced.

The Reaction Involves Simultaneous Cyclization And Dehydrogenation.

Under Similar Conditions, n-Heptane Yields Toluene. Here, Platinum (Pt) Supported Over Alumina (Al2O3) Can Also Be Used As A Catalyst.

This Reaction Is Called Aromatization Reaction.

Answer 2

$\[{C_6}{H_{14}}\]$ reacts with $\[C{r_2}{O_3}\]$ at $\[770\,K\]$ to give Benzene.

Explanation:

• When n-hexane ($\[{C_6}{H_{14}}\]$) is heated in the presence of Chromium oxide ($\[C{r_2}{O_3}\]$) or Vanadium oxide ($\[{V_2}{O_5}\]$) as a catalyst at $\[770\,K\]$, it undergoes cyclisation or aromatisation.
• Therefore, it results in the formation of Benzene.
• This reaction occurs at high temperature and pressure.
• In this reaction, the removal of hydrogen takes place and therefore, it involves dehydrogenation.
• At first, n-hexane is converted into cyclohexane.
• Then, further heating of cyclohexane at $\[770\,K\]$ results in aromatisation to give Benzene.
• The complete reaction is represented in the image below.
