Which amongst the following will be most readily dehydrated under acidic conditions?
Dehydration is easier when the carbocation formed is not destabilised by a nearby EWG. In (D) the NO₂ is far from the OH carbon, so the 2° cation is least destabilised.
Which one of the following alcohols reacts instantaneously with Lucas reagent?
Lucas test: 3° alcohols react instantaneously (immediate turbidity).
The products A and B obtained in the following reactions, respectively, are:
$3\,ROH + PCl_3 \to 3\,RCl + A$
$ROH + PCl_5 \to RCl + HCl + B$
PCl₃ + 3ROH → 3RCl + H₃PO₃; PCl₅ + ROH → RCl + HCl + POCl₃.
