Common Reducing Agents & Incompatible Functional Groups

[Dragosagaragarwal]

I always get confused between the reducing agents that where would it attack when many functional group are present in compound.
Please tell me about some of the common R.A like
Ni/Pt/Pd + H2
Sodium borohydride
Lithium aluminium hydride

Also please tell which functional groups the aabove R.A cannot reduce

Basically you are asking us to write the organic chemistry book for you.
