6. Consider the following exothermic reaction below.
2Cu2+(aq) +41 (aq)2Cul(s) + 12(aq)
a. If Cul is added, there will be a shift left/shift right/no shift (circle one).
b. If Cu2+ is added, there will be a shift left/shift right/no shift (circle one).
c. If a solution of AgNO3 is added, there will be a shift left/shift right/no shift (circle one).
d. If the solvent hexane (C6H14) is added, there will be a shift left/shift right/no shift (circle
one). Hint: one of the reaction species is more soluble in hexane than in water.

For each of the following statements, indicate whether they are true of false. ⚫ the terms primary, secondary and tertiary have different meanings when applied to amines than they do when applied to alcohols. • a tertiary amine is one that is bonded to a tertiary carbon atom (one with three C atoms bonded to it). • simple five-membered heteroaromatic compounds (e.g. pyrrole) are typically more electron rich than benzene. ⚫ simple six-membered heteroaromatic compounds (e.g. pyridine) are typically more electron rich than benzene. • pyrrole is very weakly basic because protonation anywhere on the ring disrupts the aromaticity. • thiophene is more reactive than benzene toward electrophilic aromatic substitution. • pyridine is more reactive than nitrobenzene toward electrophilic aromatic substitution. • the lone pair on the nitrogen atom of pyridine is part of the pi system.arrow_forwardThe following reactions are NOT ordered in the way in which they occur.
