The aromatic compounds bromobenzene, toluene, phenol, aniline, nitrobenzene and p-bromotoluene are to be ranked in the expected order of their reactivity towards Friedal-Crafts alkylation. Which of them are unreactive is also to be stated. Concept introduction: Aromatic compounds that contain an ortho and para directing substituent groups (except halogens) are more reactive than benzene and that contain a meta directing substituent group are less reactive than benzene. Halogens are ortho & para directing yet deactivating groups. Hence the halogen substituted benzenes are less reactive than benzene. As an exception, the aromatic rings that are either substituted by a strongly electron-withdrawing groups such as carbonyl or basic amino group that can be protonated do not react in Friedal crafts reaction, as they deactivate the ring. To rank: The aromatic compounds bromobenzene, toluene, phenol, aniline, nitrobenzene and p-bromotoluene in the expected order of their reactivity towards Friedal-Crafts alkylation. Further to state which of them are unreactive.

Question

A certain half-reaction has a standard reduction potential Ered +1.26 V. An engineer proposes using this half-reaction at the anode of a galvanic cell that must provide at least 1.10 V of electrical power. The cell will operate under standard conditions. Note for advanced students: assume the engineer requires this half-reaction to happen at the anode of the cell. Is there a minimum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the minimum. Round your answer to 2 decimal places. If there is no lower limit, check the "no" box.. Is there a maximum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the maximum. Round your answer to 2 decimal places. If there is no upper limit, check the "no" box. yes, there is a minimum. 1 red Πν no minimum Oyes, there is a maximum. 0 E red Dv By using the information in the ALEKS…

Interpretation Introduction

Interpretation:

The aromatic compounds bromobenzene, toluene, phenol, aniline, nitrobenzene and p-bromotoluene are to be ranked in the expected order of their reactivity towards Friedal-Crafts alkylation. Which of them are unreactive is also to be stated.

Aromatic compounds that contain an ortho and para directing substituent groups (except halogens) are more reactive than benzene and that contain a meta directing substituent group are less reactive than benzene. Halogens are ortho & para directing yet deactivating groups. Hence the halogen substituted benzenes are less reactive than benzene.

As an exception, the aromatic rings that are either substituted by a strongly electron-withdrawing groups such as carbonyl or basic amino group that can be protonated do not react in Friedal crafts reaction, as they deactivate the ring.

To rank:
