After which word should you place a comma?

All of us are very eager to see the presentation and we particularly look forward to the question period.

It's a compound sentence.

Read section 2. Then let me know what you think.

To determine where to place a comma in the given sentence, first, we need to identify the coordinating conjunction connecting the two independent clauses. In this case, the coordinating conjunction is "and." According to the rules of punctuation, when joining two independent clauses with a coordinating conjunction, a comma should be placed before the conjunction. So, in the given sentence, the comma should be placed after the word "presentation."

The correct sentence with the comma would be:

"All of us are very eager to see the presentation, and we particularly look forward to the question period."
