<img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/e73acea47f13be2e75a586adeb52702c-.png" /> As benzene ring increases electron density to carbon of C - 0 bond. Hence, benzylic alcohol is more reactive towards reaction with conc. HCl.

Q. Which of the following reacts fastest with conc. $H Cl$ ?

$(C H_{3})_{3} CO H$

$C H_{2} = C H - C H_{2} O H$

As benzene ring increases electron density to carbon of C - 0 bond.

Hence, benzylic alcohol is more reactive towards reaction with conc. HCl.

Q. Which of the following reacts fastest with conc. HCl ?

(CH3​)3​COH

CH2​=CH−CH2​OH

As benzene ring increases electron density to carbon of C - 0 bond. Hence, benzylic alcohol is more reactive towards reaction with conc. HCl.

$(C H_{3})_{3} CO H$

$C H_{2} = C H - C H_{2} O H$

As benzene ring increases electron density to carbon of C - 0 bond.

Hence, benzylic alcohol is more reactive towards reaction with conc. HCl.
