Hydrocarbons

Assertion : Saturated hydrocarbons are chemically less reactive.

Reason: All isomeric paraftins have same parent name.

• If both assertion and reason are true and reason is the correct explanation of assertion.

• If both assertion and reason are true but reason is not the correct explanation of assertion.

• If assertion is true but reason is false.

• If both assertion and reason are false.

The end product in the sequence would be 

C₃H₇OH $\underset{170°}{\overset{{\mathrm{H}}_2{\mathrm{SO}}_4}{\to }}$ A $\stackrel{{\mathrm{Br}}_2}{\to }$ B $\underset{\mathrm{KOH}}{\overset{\mathrm{Alc}.}{\to }}$ C

• CH₃-C$\equiv$CH

• CH₃-C(OH)=CH₂

• CH₂=C=CH₂

• CH₃-CH(OH)-CH₂(OH)

Assertion: Ortho and para-nitrophenol can be separated by steam distillation.

Reason: Para-nitrophenol is steam volatile due to intramolecular hydrogen bonding.

• If both assertion and reason are true and reason is the correct explanation of assertion.

• If both assertion and reason are true but reason is not the correct explanation of assertion.

• If assertion is true but reason is false.

• If both assertion and reason are false.
