Draw an electron pushing mechanism that demonstrates the isomerization from the cyclic isomer of glucose to the open-chain isomer.
Saccharides, such as glucose, exist in biological systems in as
open-chain and cyclic
isomers. The cyclic isomer results from the nucleophilic addition
reaction between the aldehyde
and a hydroxyl group.

Complete the electron-pushing mechanism for the E1 reaction when
2-methylbutan-2-ol is treated with 20% sulfuric acid.
Hint: The E1 mechanism involves dissociation of the hydroxyl
group from the substrate. The acid is used to convert the hydroxyl
group to a good leaving group. Do not delete any pre-drawn
bonds/charges/lone pairs.

QUESTION: Draw an arrow-pushing mechanism for the FIRST STEP of
this synthetic sequence.
In this laboratory experiment, you will synthesize a RTIL, 1-hexyl-3-methylimidazolium hexafluorophosphate, using a two-step process involving nucleophilic substitution and anion exchange. 1-Hexyl-3-methylimidazolium hexafluorophosphate and its structural analogs have long names. Therefore, they are often abbreviated as [Cn-mim X, where n = the number of carbons in the alkyl chain of the cation, ‘mim' stands for methylimidazolium and X = the anion.
