Question 9 (10 points)
Organic Reactions.

You MUST write the complete reaction by chemical formulas like the given example.
1) 3,3-dimethyl pentene + H2 O →
2) 3-methoxy butanan-2- ol + IOI →
3) ethy 2- chloro butanoate + H2 O -→ (Hydrolysis)
4) propanol + 2- bromo- 3-methoxy butanoic acid →

Answer 1

Here are the answers to your questions:

Question 1

Answer: a. The product has fewer carbon-oxygen bonds than the reactant.

Question 2

Answer: d. None of the above
Note: Tertiary alcohols generally do not oxidize to carbonyl compounds like aldehydes or ketones; they tend to resist oxidation.

Question 3

Answer: a. addition

Question 4

Answer: b. carboxylic acid and alcohol

Question 5

Answer: d. secondary amine
Note: The molecule suggested appears to be an amine as it contains a nitrogen atom bonded to hydrogen and has an implied carbon backbone.

Question 6

Answer: c. Ketone

Question 7

Answer: b. Ether

Question 8

a. CFCs (Chlorofluorocarbons) are organic compounds that contain carbon, chlorine, and fluorine atoms. They were once widely used in refrigeration, air conditioning, and aerosol propellants.
b. Are CFCs harmful to humans? Yes, CFCs can be harmful; they are not directly toxic to humans in low concentrations, but they have significant environmental effects. They contribute to ozone layer depletion, which increases UV radiation exposure, leading to skin cancer and other health issues. Moreover, CFCs are greenhouse gases, which contribute to climate change.

Question 9

1. C5H10 + H2O → C5H12O (after hydration)
2. C5H12O2 + IOI → C3H8O2 + I2 (may not be straightforward, further clarification may be needed on the reaction)
3. C5H9ClO2 + H2O → C5H10O2 + HCl (Hydrolysis)
4. C3H8O + C8H14O2 → C11H18O3 (Assuming esterification/formation of an ester)
