—Knowledge of the rate equations for the hydrolysis of halogenoalkanes can be used to provide evidence for SN1 and SN2

Understand that knowledge of the rate equations for the hydrolysis of halogenoalkanes can be used to provide evidence for SN1 and SN2 mechanisms for tertiary and primary halogenoalkane hydrolysis.

Use —knowledge of the rate equations for the hydrolysis of halogenoalkanes can be used to provide evidence for sn1 and sn2 to connect the rule to the data and decision in the question.

This matters because —knowledge of the rate equations for the hydrolysis of halogenoalkanes can be used to provide evidence for sn1 and sn2 determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —knowledge of the rate equations for the hydrolysis of halogenoalkanes can be used to provide evidence for sn1 and sn2 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.
