The correct options for the products A and B of the following reactions are:

Consider the above reaction, and choose the correct statement :

Main product formed during a reaction of \( 1 \)-methoxy naphthalene with hydroiodic acid are:

Given below are two statement: one is labelled as Assertion (A) and the other is labelled as Reason(R).
Assertion (A): Synthesis of ethyl phenyl ether may be achieved by Williamson synthesis.
Reason (R): Reaction of bromobenzene with sodium ethoxide yields ethyl phenyl ether.
In the light of the above statements, choose the most appropriate answer from the options given below:

An organic compound A \( (\mathrm{C_6H_6O}) \) gives dark green colouration with ferric chloride. On treatment with \( \mathrm{CHCl_3} \) and \( \mathrm{KOH} \), followed by acidification gives compound B. can also be obtained from compound C on reaction with pyridinium chlorochromate (PCC).

The major product \( (P) \) in the following reaction is:

The major product formed in the following reaction is:

The correct order of their reactivity towards hydrolysis at room temperature is:

Given below are two statements :
Statement-I : \( 2 \)-methylbutane on oxidation with \( \mathrm{KMnO_4} \) gives \( 2 \)-methylbutane-\( 2 \)-ol.
Statement-II : \( n \)-alkanes can be easily oxidised to corresponding alcohols with \( \mathrm{KMnO_4} \).
