Question

Identify A in the given chemical reaction. CH$_2$=CH-CH(CH$_3$)-CH$_3$ $\xrightarrow{Mo_2O_3, 773 K, 10-20 atm}$ A (major product)

• A. A
• B. B
• C. C
• D. D

Hint:

Transition metal oxides like $Mo_2O_3$ or $V_2O_5$ act as catalysts for various hydrocarbon transformations including dehydrogenation or selective reduction.

Answer 1

The Correct Option is B

Step 1: The reagents $Mo_2O_3$ at high temperature and pressure are typically used for the hydrogenation or aromatization of hydrocarbons.
Step 2: In the presence of hydrogen (often implied in these industrial catalyst conditions) or via rearrangement/stabilization, the alkene 3-methylbut-1-ene is reduced to the corresponding alkane.
Step 3: The alkane formed from this carbon skeleton is 2-methylbutane (isopentane).
