I want to connect single ended clock to a MRCC pin in XC7v200T. Where to check a particular pin is positive or negative?

The naming convention on the pins should tell you.
It follows this pattern
IO indicates it is a user IO
L tells you it is part of a pair.
XX will be a number to indicate which pair in the bank it is.
Y will indicate either P or N side of the pair.
ZZZ is usually for some special function
# tells you the bank number.
is a user IO that is the part of the 13th pair in bank it is also in memory byte group 2, and it is a multi region CCIO.
The number indicates it is located in bank 34.
You could also open the IO pin planning view post synthesis and lock the single ended clock to the P-side of any MRCC clock pair in the desired bank

there is a packaging and pinout guide.
you can use table 2-4 to download the ASCII pinout file.
