Scheme and others questions

[flowersa]

Hi, there are some things I have doubts about ...

Is Scheme and Plan means the same thing?

Is it correct to understand "hatched" as conspire to devise?

What is "Behalf" on Obama's behalf? I always had troubles with this word

"The scheme Dunn hatched on Obama’s behalf revolved around a simple transaction. Every time he did an event for a candidate, Hopefund would require the
beneficiary to set up a registration system and then turn
over the attendees’ email addresses to the PAC."

Hi Bhaisahab ...

As for "Behalf of" In the Hebrew dictonary it writes "In the name of" or "On behalf of someone" What more fits for it?

Thanks for fixing
