The substrate is the same in parts a and b, however the mechanism that proceeds is different. Explain how the choice of solvent
GenaCL600 [577]

Answer:

See explanation

Explanation:

The reaction of a benzyl bromide with a nucleophile may proceed by SN1 or SN2 mechanism depending on the nature of the solvent used.

Since SN1 reaction involves the formation of a carbocation, it usually predominates in the presence of a poor nucleophiles and protic solvents. Hence when methanol is used as solvent and a poor nucleophile is used, SN1 mechanism predominates.

However, when acetone which is an aprotic solvent is used in the presence of a good nucleophile, SN2 reaction mechanism predominates.

Identify the molecule with the strongest intermolecular force <br> HF<br> HCl<br> Hl<br> HBr
Dominik [7]
Hey there !:

HF s molecule with the strongest intermolecular force

<span>HF > HI > HBr > HCl</span><span>

</span>The main factor of influence at the boiling point is the question of intermolecular forces, but not only that, the molar mass also has influence (the greater the molar mass, the greater the boiling point). Note that the only one forming hydrogen bridges is the HF, therefore the largest boiling point, iodine, bromine and chlorine have the same type of intermolecular (permanent dipole) connections as they are polar, and what will differentiate the boiling point of each one is the molar mass.
