**Question: Which is the most stable radical?****Options:**- **A.** (Structural Diagram)- **B.** (Structural Diagram)- **C.** (Structural Diagram)- **D.** (Structural Diagram)**Explanation of Structural Diagrams:**- **Option A:** This structure is a carbon radical. The radical is positioned on a sp^2 hybridized carbon, adjacent to a double bond. This is known as an allylic radical.- **Option B:** This diagram depicts a radical on a secondary carbon. The radical is not adjacent to a double bond.- **Option C:** This structure shows a tertiary carbon radical. The radical is positioned on the carbon that is bonded to three other carbon atoms, providing hyperconjugation and inductive effects.- **Option D:** This depiction illustrates a primary carbon radical adjacent to a double bond, making it another allylic radical like in Option A, but on a primary carbon.**Answer and Explanation:**The most stable radical out of these options is usually the one with the most significant stabilizing factors such as resonance and hyperconjugation. Tertiary radicals (option C) are generally more stable than secondary and primary radicals due to higher hyperconjugative stabilization.Therefore, **option C** is the most stable radical, given the tertiary carbon provides significant stabilization.

A Water Quality Standard will be developed for radioactive isotope “Iron-55” which has physical (radioactive) and biological half-lives of 2.7 and 1.6 years, respectively. Through toxicological studies scientists decided “spleen” as the critical organ and the critical accumulation of Iron-55 in spleen has been determined to be 0.5 gram. Assuming radioactive exposure is only due to drinking water consumption and average life expectancy is 75 years. a) What should be the Maximum Concentration Level (MCL) as mg/L for Iron-55 in drinking water. b) How long does it take to eliminate 95% of this radioactive isotope from human spleen after the person gives up on drinking water contaminated with Iron-55?

3) Carbon-14 is constantly being produced in the upper atmosphere, and the amount is in equilibrium. As long as an organism is alive, it keeps its carbon isotopes in balance with the atmosphere, but at soon as it dies, it stops taking up new 14C, and so the geologic clock starts. You found a shell buried in sedimentary layers, which has 6% of its original 14C left. Determine the age of the shell. Show your work.
