ANSWER SAMPLE QUESTIONS
1. How would you describe the difference between saturated and unsaturated hydrocarbons and
what is a distinguishing feature of aromatic hydrocarbons?
2. Did you observe any differences between the reactivity of cycloalkanes or cylcoalkenes
relative to the straight chain hydrocarbons in any of the tests where they were compared?
Describe any differences you did observe.
3. Should the cyclic compounds behave differently in these tests compared to the straight chain compounds? Explain why or why not.
4. What is your insight about this experiment?
1..Saturated Hydrocarbons — contain only carbon- carbon single bonds. Unsaturated Hydrocarbons — contain carbon- carbon double or triple bonds (more hydrogens can be added). In the carbon-carbon double bond, two pairs of electrons are being shared, leaving the carbon free to bond to two other things
2.The C−C=C angle in alkenes normally is about 122o, which is 10o larger than the normal C−C−C angle in cycloalkanes. This means that we would expect about 20o more angle strain in small-ring cycloalkenes than in the cycloalkanes with the same numbers of carbons in the ring.
3.Heterocyclic compounds can be divided into two groups: (i) aromatic and (ii) nonaromatic. Five-membered heterocyclic compounds may contain a single heteroatom. Examples include pyrrole, furan, and thiophene. The five-membered rings may also contain more than one heteroatom (i dont have any explain sorry:>>)
4.o get to where we want to go, we need to experiment with forms of societal engagement that are more critical and reflective. We need to grow positive examples.
They are there for a reason
That reason is to keep you safe
A laboratory is a place of the unknown.
You might inhale toxic fumes or touch a toxic chemical.
The rules and safety guidelines are to be followed to ensure the safety of a studet in the laboratory
