AP FRQ WORKED ANSWER ARCHIVE
Here you’ll find the worked answers to FRQs from previous AP Chemistry exams. Every released FRQ from 1990 to 2023* has a worked answer.
*2020 was a COVID interrupted year, and no formal exam questions were released into the public domain by the College Board, although AP teachers do have access to questions from 2020.
Prior to 1990, some additional FRQ answers are available, others are not (Blue = available, Grey = not yet available). If you require an answer to a specific problem that is not yet available, just ask.
The FRQs themselves are linked here.

2020 FRQs and ANSWERS
In 2020 the AP chemistry exam was COVID affected, and the exam was offered in an online format only, with approx. 30, different FRQs being used in various combinations in the exams
The questions that a particular teacher’s students were given were released to that individual teacher, but there were no collective, released FRQs in the traditional sense in 2020
The questions that were used in 2020 were also released into the AP Classroom question bank, so that teachers could access them
As such, the 2020 FRQs and their ANSWERS are not available in the same manner as other years
