I have the following three sentences:
1/ We will show what is the relation of this parameter to other existing properties.
2/ We will show what the relation of this parameter is to other existing properties.
3/ We will show what the relation of this parameter to other existing properties is.
I think that 2 is wrong. I strongly prefer 1/ but I do not know if it is correct. 3 is surely correct but it sounds cumbersome.
