In
Electron releasing groups, except halogens, normally are activators and ortho & para directors. Electron withdrawing groups normally are deactivators and meta directors. Halogens are ortho & para directing but are deactivating.

Whether N,N-dimethylamino group is an activator or deactivator and whether it is a, o-, p-director or m-director.
b)
Interpretation:
Whether cyclopentyl group is an activator or deactivator and whether it is an o-, p-director or m-director is to be stated.
Concept introduction:
In aromatic substitution reactions the activating or deactivating and orienting effects of a substituent attached to the benzene ring can be decided from its resonance and inductive effects. The orientation is decided by the resonance effect while the activating or deactivating effect is decided both by resonance and inductive effects. Both effects may reinforce or oppose each other. However the resonance effect is much stronger than the inductive effect.

Generate a molecular orbital diagram but this time using a different approach that draws on your knowledge and ability to put concepts together. First use VSEPR or some other method to make sure you know the ground state structure of the molecule. Next, generate an MO diagram for BH2. Sketch the highest occupied and lowest unoccupied MOs of the BH2 fragment. These are called frontier orbitals. Now use these frontier orbitals as your basis set for producing LGO's for B2H6. Since the BH2 frontier orbitals become the LGOS, you will have to think about what is in the middle of the molecule and treat its basis as well. Do you arrive at the same qualitative MO diagram as is discussed in the book?
