Yes, It will pass the lexical phase. 

There is a specific rule in "integer constant creation" that you can not have a blank space between a number.

In the above line after 5th 1, "1 1", cause an error.  This error is a grammatical error. Hence It will be not pass syntax analysis. Hence syntax error will be generated and reported at compile time.
