Both the acetamido (-NHCOCH3) and bromo (-Br) substituents are ortho, para directors. Even though the acetamido group is much la
rger than the bromo group, the -Cl is still introduced next to the acetamido group in spite of the greater steric hinderance at this site. Why?

Answer:
Explanation has been given below
Explanation:
- Attachment of -Cl group at ortho position to acetamido group can be explained in terms of hydrogen bonding formation.
- A hydrogen bonding can be formed between proton attached with N atom in acetamido group and Cl atom at ortho position. This leads to a formation of a stable 5-membered ring structure.
- Hence ortho substitution by Cl is favorable process.
- There is no hydrogen bonding possible between Br and Cl atom in ortho position. Therefore Cl prefers para position to avoid steric hindrance.
- Structure of hydrogen bonded structure has been shown below.

Answer:
A beaker
Step-by-step explanation:
Specifically, I would use a 250 mL graduated beaker.
A beaker is appropriate to measure 100 mL of stock solution, because it's easy to pour into itscwide mouth from a large stock bottle.
You don't need precisely 100 mL solution.
If the beaker is graduated, you can easily measure 100 mL of the stock solution.
Even if it isn't graduated, 100 mL is just under half the volume of the beaker, and that should be good enough for your purposes (you will be using more precise measuring tools during the experiment).
