Kolbe-Schmidt reaction
Schmidt reaction
Kolbe's reaction
Assertion : (CH3)3CCOC(CH3)3 and acetone can be distinguished by the reaction with NaHSO3.
Reason : HSO3- is the nucleophile in bisulphite addition.
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.
Assertion : Cyclohexanone exhibits keto-enol tautomerism.
Reason : In cyclohexanone, one form contains the keto group (>C=O) while other contains enolic group (- C=C- OH).

If both assertion and reason are false.
Assertion: Phenol is more reactive than benzene towards electrophilic substitution reaction.
Reason : In the case of phenol, the intermediate carbocation is more resonance stabilised.
If both assertion and reason are true and reason is the correct explanation of assertion.

A.
If both assertion and reason are true and reason is the correct explanation of assertion.
Saytzeft's rule : The alkene formed in greatest ( amount is the one that corresponds to removal of the hydrogen from the (beta-carbon having the fewest hydrogen substituent.
In case of 2° and 3° alc. Saytzeft's rule is followed
C2H5-(CHOH)-CH3 H3C-CH=CH-CH3 + H2O
Assertion : Ethers behave as bases in the presence of mineral acids.
Reason : It is due to the presence of lone pair of electrons on the oxygen.

If assertion is true but reason is false.
If both assertion and reason are false.
