Does compiler sees these uses of else-if as the same thing?

Instead of this -

if(*condition1*){
    *statement/s*
}
else if(*condition2*){
    *some different statement/s*
}

if this is used -

if(*condition1*){
        *statement/s*
}
else
    if(*condition2*){
        *some different statement/s*
    }

Does the compiler sees both of these as same things, because white-space does not matter in C, and the 2nd if gets associated with the else statement.

Similarly, for this, do they mean the same?

for(*initialization*;*condition*;*increment*)
    ;

and this -

for(*initialization*;*condition*;*increment*);

where ; is a null statement.

If yes, then why?

All leading and trailing whitespaces are ignored.

The else if conditions are same. but the for loop is different, because, 

for(*initialization*;*condition*;*increment*)
                ;

here before the ; you can give the statements to execute and it will be executed. but if you specify the ; without the statements then if the condition is true nothing will be done.

Yes both if and for statements are the same. For C, Space, newline doesn't matter.

Yes. Whitespace (apart from its presence at all) truly is insignificant in C. Most C implementations collect whitespace while lexing.

It doesnt matter at all if you add newlines or whitespaces
