You Are Given a Bottle of an Organic Liquid and Told

question 10

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.

Definitions:

Multipolar

A type of neuron that contains one axon and multiple dendrites, allowing for the transmission of nerve impulses to and from various connections.

Resting Membrane Potential

The electrical charge difference across the cell membrane when the cell is not actively transmitting signals, typically around -70mV for neurons.

Local Potential

Depolarization that is not propagated and that is graded or proportional to the strength of the stimulus.

Summate

To add together or accumulate to a total; in physiology, refers to the additive effect of repeated stimuli on a nerve or muscle.
