This structure has a lower pKa than usual because the conjugate base of the structure has unusual stability.
Using the provided resonance structures, draw the curved electron-pushing arrows to show the deprotonation step. Then, draw the curved electron-pushing arrows to show the interconversion between resonance hybrid contributors.
Be sure to account for all bond-breaking and bond-making steps
For an SN1 reaction, which of the following is the correct order from the
given statements below: (1) The nucleophile attacks both from the front
and from the back of the planar carbocation. (II) The nucleophile attacks
from a backside position. (II) The halide ion as the leaving group leaves
initially. (IV) The halide ion as the leaving group leaves subsequently. (V)
The halide ion as the leaving group leaves simultaneously as the
nucleophile approaches. (VI) The product is formed. (VII) A stable
carbocation is formed. (VIII) A product with inversed chirality is formed.

Heating an alcohol in the presence of sulfuric or phosphoric acid will cause a dehydration to occur: the removal of the elements of water from a molecule, forming an alkene. The reaction usually follows an E1 mechanism. The SN1 pathway is suppressed, both by heating the reaction mixture (more energy promotes the elimination pathway) and by using a strong acid whose conjugate base is a poor nucleophile.
Draw curved arrow(s) to show how the alcohol reacts with phosphoric acid.
