The structural formula of picric acid is :

Phenol reacts with aqueous bromine to give :

• 

• 

•  + 

• 

Assertion : t-Butyl methyl ether is not prepared by the reaction of t-butyl bromide with sodium methoxide.

Reason : Sodium methoxide is a strong nucleophile.

• 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.
