TFA and PFOA are members of the same PFAS “family”

What the figure shows
Ball-and-stick models of two molecules side by side: TFA, a small molecule with two carbon atoms, and PFOA, a chain of eight carbon atoms. Both carry fluorine atoms along the carbon chain and an acid group at one end. An arc labelled PFAS joins the two. Title: TFA and PFOA are members of the same PFAS “family”.
