Vedclass · Answer

(B) The formation of a $benzyne$ intermediate requires the presence of an ortho-hydrogen atom relative to the leaving group to allow for the elimination of $HX$ (or similar) to form the triple bond in the ring.$A$. $1-fluoro-2-methoxybenzene$ has an ortho-hydrogen,so it can form $benzyne$.$B$. $1-chloro-2,6-dimethylbenzene$ does not have any hydrogen atoms at the ortho positions relative to the chlorine atom (both ortho positions are occupied by methyl groups). Therefore,it cannot undergo elimination to form a $benzyne$ intermediate.$C$. $Chlorobenzene$ has ortho-hydrogens and can form $benzyne$ under strong basic conditions.$D$. The $o-aminobenzoic$ acid derivative (anthranilic acid) forms $benzyne$ via diazotization followed by the loss of $N_2$ and $CO_2$.Thus,$benzyne$ is not observed in $1-chloro-2,6-dimethylbenzene$.
