Which of the following compounds is aromatic?

AI Thread Summary
The discussion centers on identifying aromatic compounds based on Huckel's 4n+2 π electron rule. Options A, B, C, and D are evaluated, with A dismissed due to potential non-planarity, while B, C, and D are deemed anti-aromatic due to having 8 and 12 π electrons, respectively. The user expresses confusion about the correct answer and the orientation of the attached image. Questions arise regarding the presence of unhybridized p orbitals in the molecules discussed. The conversation highlights the importance of understanding molecular structure and electron configuration in determining aromaticity.

1. Homework Statement : please refer to the picture attached

Homework Equations

: [/B]A compound is aromatic if it is planar and it satisfies Huckles 4n+2 Π electron rule.

The Attempt at a Solution

: [/B]
Option A is not correct...I don't know why...just speaking from intuition..probably its not planar due to angular strain..I don't know..
Option B is also not correct because we have 8Π electrons which makes it anti aromatic.
Option C also is incorrect as we have 12 Πelectrons making it antiaromatic.
Same is true for Option D.
Then which one is correct? Is it option A as it is the only option I discarded based on intuition.

Where are the unhybridized p orbitals in that molecule?

Don't you know how double bonds are formed?
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
