Are all the following expressions correct? What are the differences?
- I will arrange for the manuscript to be sent on to you.
- I will arrange that the manuscript will be send to you in time.
- I will make sure of the manuscript to be sent to you in time
*I will arrange for the manuscript to be sent (on) to you (note that “sent on” suggests it is going via other people first)
*I will arrange for the manuscript to be sent to you on time (“in time” may mean “when I get around to it”, suggesting it is not important to the sender [see comments])
*I will make sure that the manuscript is sent to you on time
The differences, of course, now that the sentences are grammatically correct, are that the last two mention that they will be sent on time (ie, so that they will arrive by the necessary time). The first does not have this time element, although the suggestion is that it will be done within a reasonable amount of time.
I would suggest you use the English language learners stack exchange for such questions in future:
