The last one is very tricky N O N H N H 10e- aromatic 12e- antiaromatic 6e- aromatic the oxygen contribues 2 e- 10e- aromatic the nitrogen contributes 2 e- nonaromatic sp3 carbon 12e- antiaromatic nonaromatic. QUESTION 1 Identify from the following compounds which one is antiaromatic. Anti- aromatic compounds are unstable.

Conditions for compounds to be anti-aromatic. 1 11 IV V IL III IV OV QUESTION 2 Identify from the following compounds those having conjugated double bonds. Pi bonds are in a cyclic structure and 2.

V and VI both have 4e and planar structure. Being planar and cyclic structure completely conjugated system. The molecule has to be planar.

So one difference brings a new class of compounds that are structurally very similar to aromatic compounds however their properties and stability are on the exact opposite of the spectrum. Which of the following species are antiaromatic. Which one of the following compounds is most acidic -AIPMT-2005 1 OH NO 2 2 OH CH 3 3 OH 4 ClCH 2 CH 2 OH 9.
