Current Question (ID: 21293)

Question:

$\text{Identify A in the given chemical reaction:}$ $\text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{CH}_2\text{CH}_3 \xrightarrow{\text{Mo}_2\text{O}_3, \ 773 \text{ K}, \ 10-20 \text{ atm}} \text{A (major product)}$

Options:

1. $\text{Benzene}$
2. $\text{Cyclohexane}$
3. $\text{Methylcyclopentane}$
4. $\text{Toluene}$

Solution:

$\text{Hint: The benzene ring is formed in the product.}$ $\text{n-Alkanes having six or more carbon atoms on heating to 773K at 10-20 atmospheric pressure in the presence of oxides of}$ $\text{vanadium, molybdenum, or chromium supported over alumina get dehydrogenated and cyclized to benzene and its homologues.}$ $\text{This reaction is known as aromatization or reforming.}$ $\text{The reaction is as follows:}$ $\text{C}_6\text{H}_{14} \xrightarrow{\text{Mo}_2\text{O}_3, \ 773 \text{ K}, \ 10-20 \text{ atm}} \text{C}_6\text{H}_6 + 4\text{H}_2$
