A polymer X is biodegradable and is obtained from the monomers Y, Z. What are Y and Z?
Show Hint
The Correct Option is D
Solution and Explanation
Step 1: Identifying the Biodegradable Polymer Components.
Biodegradable polymers are those that can be broken down by microorganisms into natural substances such as water and carbon dioxide.
Step 2: Recognizing Monomers.
- A well-known biodegradable polymer is Polyhydroxyalkanoates (PHAs), which are derived from hydroxy acids.
- The monomers given in option (4) contain hydroxyl (-OH) and carboxyl (-COOH) functional groups, making them ideal candidates for forming biodegradable polymers.
- Other options include amino acids and linear dicarboxylic acids, which are less commonly used in biodegradable polymer formation.
Step 3: Conclusion. Since hydroxy acids serve as monomers for biodegradable polymers like polyhydroxybutyrate (PHB), option (4) is the correct choice.

Given the function:
\[ f(x) = \begin{cases} \frac{(2x^2 - ax +1) - (ax^2 + 3bx + 2)}{x+1}, & \text{if } x \neq -1 \\ k, & \text{if } x = -1 \end{cases} \]
If \( a, b, k \in \mathbb{R} \) and \( f(x) \) is continuous for all \( x \), then the value of \( k \) is:
Given the function:
\[ f(x) = \begin{cases} \frac{2x e^{1/2x} - 3x e^{-1/2x}}{e^{1/2x} + 4e^{-1/2x}}, & \text{if } x \neq 0 \\ 0, & \text{if } x = 0 \end{cases} \]
