question 34

Multiple Choice

You are given a bottle of an organic liquid and told it must be either cyclohexane or 1-hexene.Which of the following statements is (are) true about these two compounds?

• A)The two compounds can be differentiated by their mass spectra because they will have molecular ion peaks at different m/z.
• B)1-Hexene will show an absorption at 1650 cm^-1 but cyclohexane will not.
• C)Both cyclohexane and 1-hexene will show C-H absorptions at about 2950 cm^-1.
• D)Statements (1-Hexene will show an absorption at 1650 cm^-1 but cyclohexane will not)and (Both cyclohexane and 1-hexene will show C-H absorptions at about 2950 cm^-1)are both true.
• E)Statements (The two compounds can be differentiated by their mass spectra because they will have molecular ions at different masses),(1-Hexene will show an absorption at 1650 cm^-1 but cyclohexane will not),and (Both cyclohexane and 1- hexene will show C-H absorptions at about 2950 cm^-1)are all true.
