Question

Would you expect the above compound to be aromatic?

Yes
No
Choose the correct explanations for the aromaticity of the compound. Salectal that apply.
The lone pairs on the nitrogen atoms do not corbute to aromat city.
The lone pairs on the nitrogen atoms do contribute to aromaticity.
The lone pairs on the nitrogen atoms occupy sp² hybridad orials.
The lone pairs on the nitrogen atoms occupy s hybriditals
One of the lone pairs on the oxygen atom (inside the ring) occupies apcrbital, giving a continuous system of overlapping p orbitals containing six electrons.
One of the lone pairs on the oxygen atom (outside the ring) occupies a p orbital, giving a continuous system of overlapping p orbitals containing sixx electrons.
Identify which of the following compounds is expected to be a stronger base.
Compound A
Compound B
C Compound A
C Compound B
Choose the correct explanation(s) for the above observation. Select all that apply.
The lone pair on the nitrogen atom in compound B is localized and available to function as a base.
The lone pair on the nitrogen atom in compound B is delocalized and is participating in aromaticity.
The lone pair on the nitrogen atom in compound A is localized and available to function as a base.
The lone pair on the nitrogen atom in compound A is delocalized and is participating in aromaticity.
The nitrogen atom in compound A is unavailable to function as a base, because that would cause a loss of aromaticity.
The nitrogen atom in compound B is unavailable to function as a base, because that would cause a loss of aromaticity.

Answer 1

To find out if the given compound is aromatic or not use Huckle rule of aromaticity

a cyclic, planar molecule has 4n+2 π electrons, it is considered aromatic.
