19.9—Draw the structural formulae of the repeat units of the polymers in 19.8

Be able to draw the structural formulae of the repeat units of the polymers in 19.8.

Use —draw the structural formulae of the repeat units of the polymers in 19.8 to connect the rule to the data and decision in the question.

This matters because —draw the structural formulae of the repeat units of the polymers in 19.8 determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —draw the structural formulae of the repeat units of the polymers in 19.8 to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: use the formula and units given in the question, show the substitution and interpret the result; the calculation alone is not the conclusion.
