Question

Schemes 1 and 2 describe the conversion of P to Q and R to S respectively. Scheme 3 describes the synthesis of T from Q and S. The total number of Br atoms in a molecule of T is:

Open in App

Solution

When phenol is treated with bromine in the presence of a non-polar compound like carbon disulfide, results in the formation ortho-bormophenol and para-bromophenol. The major product for this reaction is p-bromophenol because this position is sterically unhindered.
