Let's take a common compound Cyclopropane .
Carry out the following reactions on it in sequence ..
Molecular Mass of the product is A .
Aromaticity of the product is B .
Values assigned ⎩ ⎪ ⎨ ⎪ ⎧ Non-aromatic = 2 Aromatic = 4 Anti-aromatic = 6
Enter your answer as A × B .

Bro it should be N i ( C N ) X 2 not N i ( C N ) X 4
But wont there be free radical substitution with br2?

No, halogens give free radical substitution in presence of sunlight or some other radical generatong source only.
Isn't there a chance for carbocation rearrangement in the reaction?
C H X 2 ( O H ) − C H X 2 − C H X 2 ( O H ) with H B r
The product formed in this case would be C H X 3 − C H ( B r ) − C H X 2 ( O H ) instead of C H X 2 ( B r ) − C H X 2 − C H X 2 ( O H ) .

No chance , as at that position C+ is unstable Due to -I effect of O
after adding Br2 to ethene ,the Br should be anti position so NaNH2 should not eliminate??
Log in to reply
what are you saying! the molecule is symmetric , there is nothing like anti in it!
After adding LiAlH4, you added H+ you must also mention heating as ethene is formed at 170°C.
Forgot , done !
