Question : REFER THE CLIPPING.

Answer 1

the above given figure is the structure of-
⭐cyclo Octa 1,3,5,7 tetraene

1) if we see in the above compound-
it has 8 π electrons.
and we know that if a compound is aromatic it must follow HUCKEL RULE .

acc. to huckel rule -
the π ele. of the compound = 4(n+2) π electron
8π ele. = 4(1+2) = 12 π electon

so, show the compound present above do not follow the huckel rule so it is not an aromatic compound.

2). the decreasing order of acidic behaviour-
for n - hexane , ethyne , benzene.

order is - ethyne > benzene> n- hexane.

⭐ how is the decreasing order of acidic behaviour.
