—The general formula of alkenes and understand that alkenes and cycloalkenes are hydrocarbons which are unsaturated (have

Know the general formula of alkenes and understand that alkenes and cycloalkenes are hydrocarbons which are unsaturated (have a carbon-carbon double bond which consists of a σ bond and a π bond).

Use —the general formula of alkenes and understand that alkenes and cycloalkenes are hydrocarbons which are unsaturated (have to connect the rule to the data and decision in the question.

This matters because —the general formula of alkenes and understand that alkenes and cycloalkenes are hydrocarbons which are unsaturated (have determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —the general formula of alkenes and understand that alkenes and cycloalkenes are hydrocarbons which are unsaturated (have 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.
