What are the functional groups in vicodin?

Amide, phenol, aromatic ether, ketone, and tertiary amine.

Explanation:

Vicodin is a combination of two pain relievers: acetaminophen (Figure A) and hydrocodone (Figure B).

Acetaminophen contains two functional groups:

An amide group (1) A phenol group (2)

Hydrocodone has four functional groups:

Two aromatic ethers (1 and 2). A ketone (3) A tertiary amine  (4)

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

Ido not understand.
