Yes, The Reduciton of Nitro Compounds by Sn/HCl is regioselective That means irrespective of where is te double bond in pos. with Double Bond it is going to reduce -NO2 Group to -NH2 Group.
One such Example is:
When NitroBenzene Compound Reacts with Sn/HCl we will get the end compound as Aniline.
Means Benzene has a NO2 group at main position and when reacted with Sn/HCl it gets -NH2 at the same position.
Hope it helps. Cheers!@!@!
