What is Fitzgerald trying to achieve when he opens this chapter?

Fitzgerald mentions all of they party guests names as a way to show us who the type of people are that Gatsby interacts with and what crowd he gets along with. The people seem to be rich and maybe they just come for a good time or to party and not to speak with the host himself. This can connect with the theme of illusion because we get the impression that they live the good life and party all the time, but it sounds as though they have more to their life and the party’s they attend are distraction for them. It can also create the illusion that Gatsby knows all these important people so it makes him think he has friends and he is important to people.

If you read the names aloud they all sound like animals, pests or not nice words.
