What is X in the following reaction?





Step 1: Oxidation with KMnO₄ - The given starting compound is a dicarboxylic acid. - Treatment with \( KMnO_4 \) and \( H_2SO_4 \) under heat leads to oxidative cleavage, forming a cyclic ketone. 
Step 2: Bromination with \( Br_2 \) under UV light - The cyclohexanone undergoes bromination via radical substitution at the allylic position, leading to the formation of bromo-cyclohexene.
If the roots of $\sqrt{\frac{1 - y}{y}} + \sqrt{\frac{y}{1 - y}} = \frac{5}{2}$ are $\alpha$ and $\beta$ ($\beta > \alpha$) and the equation $(\alpha + \beta)x^4 - 25\alpha \beta x^2 + (\gamma + \beta - \alpha) = 0$ has real roots, then a possible value of $y$ is:
