Asertion: trans-butene-2 on reaction with bromine forms racemic mixture. Reason: trans-Compound in trans addition forms two types of stereoisomers.
1 If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
2 If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
3 If the Assertion is correct but Reason is incorrect.
4 If both the Assertion and Reason are incorrect.
5 If the Assertion is incorrect but the Reason is correct.
Explanation:
: In trans - compound in trans addition forms a racemic mixture Hence, the assertion and reason both are false.

In the given reaction $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}=\mathrm{CHCH}_3 \stackrel{\mathrm{x}}{\longrightarrow}$ $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{COOH}+\mathrm{CH}_3 \mathrm{COOH}$ The $\mathrm{X}$ is
1 Cone. $\mathrm{HCl}+$ Anhy. $\mathrm{ZnCl}_2$
2 Anhyd. $\mathrm{AlCl}_3$
3 $\mathrm{KMnO}_4 / \mathrm{OH}^{-}$
4 $\mathrm{C}_2 \mathrm{H}_5 \mathrm{ONa}$
Explanation:
: $\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{COOH}+\mathrm{CH}_3 \mathrm{COOH}$ This reaction is oxidative cleavage $\mathrm{KMnO}_4 / \mathrm{OH}^{-}$act as an oxidizing agent. Hence, pent-2-ene react and ethanoic acid.
