To determine the possessive form of a noun, you generally need to add an apostrophe and an "s" at the end of the noun if it is singular, or just an apostrophe at the end if it is plural. Here are some examples:

1. The car of my friend = My friend's car
2. The books of the students = The students' books
3. The tail of the cat = The cat's tail
4. The toys of the child = The child's toys
5. The house of the Smiths = The Smiths' house
6. The shoes of the women = The women's shoes
7. The laptop of the teacher = The teacher's laptop
8. The hat of the boy = The boy's hat

Please note that in some cases, if a plural noun already ends with an "s", you can just add an apostrophe at the end to show possession. For example, "The parents of the students = The students' parents."
