Answer key for AIEEE 2012 Online Exam held on 12th May

Non aromatic means that the ring is either
1.) non planar
2.) the whole ring is not in conjugation

Anti aromatic on the other hand means that the ring is planar and in complete conjugation with 4n electrons.

Aromatic is same as anti just with 4n+2 electrons.

Absolutely correct. I would just like to add that compounds with 7 or greater membered rings are not planer, unless they are aromatic (like cycloheptatriene with a + charge on the non-double-bonded carbon). In other words these larger compounds tend to go out of the plane to achieve stability, but don't do so if they can achieve aromaticity (only in case of 7 membered ring)

But a 8 or greater membered ring can never be planar, hence cyclooctatetraene isn't planar and hence it isn't aromatic or antiaromatic, thus it's non-aromatic.

Is answer to question 12 in physics correct (34.5 J)

[kanikak]

What is the answer of basicity question?
What is the answer of Q.42?

[udit09]

I think that the answer to Q12 is 34.5 J, I'm not sure about it.

The answer of the basicity question will be 1>3>2>4 according to me. The answer of question 42 will be 0.53 V.
