When phenol reacts with chloroform and aqueous NaOH solution, it give salicylaldehyde. CHCl 3+ OH - H 2 O + CCl 3- CCl 3- arrow underset text dichlorocarbene CCl 2+ Cl -

Q. In the reaction of phenol with chloroform and aqueous solution of $N a O H$ at $7 0^{\circ} C$ , the electrophile attacking the ring is

$C H C l_{3}$

$C H C l_{2}$

$CC l_{2}$

$COC l_{2}$

When phenol reacts with chloroform and aqueous $N a O H$ solution, it give salicylaldehyde.
$C H C l_{3} + O H^{-} H_{2} O + CC l_{3}^{-} CC l_{3}^{-} \to dichlorocarbene CC l_{2} + C l^{-}$
