An aromatic compound  on oxidation with acidic   gives dibasic acid.The compound (A) on nitration gives three isomeric nitro derivatives.The compound (A) is:

If A = {x : x N, x is a factor of 6} and B = {x N : x is a factor of 8} then is

When we have to find intersection of two sets, we have to find their common elements. When we have to find union of two sets, we have to consider all the elements of both the sets.

Which of the following is not an intra molecular redox reaction?

The roster form of the set A = {x : x N, x < 8} is

Roster form gives us list of all elements of the sets. Set builder form gives the details of the set in compact form.

The appropriate reagent for the following transformation is:
