CHXI13:HYDROCARBONS

318104 Assertion :
The presence of ${Ag}^{+}$ enhances the solubility of alkenes in water.
Reason :
Alkenes are weakly polar in nature.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.

2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.

3 Assertion is correct but Reason is incorrect.

4 Assertion is incorrect but Reason is correct.

Explanation:

${Ag}^{+}$ forms complex with the alkene by $p π - d π$ bonding giving an ion and, thus the solubility increases.
