- OH group present on benzene due to +R effect activate towards electrophilic substitution reaction and are o -, p -directing. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/140c6b16efa18f33276ab25cb5ffc57f-.png" /> Therefore, electrophile favours attack on electron rich o - and p - positions.

$- O H$ group present on benzene due to $+ R$ effect activate towards electrophilic substitution reaction and are $o$ -, $p$ -directing.

Therefore, electrophile favours attack on electron rich $o$ - and $p$ - positions.
