Q
Q: Which of the following coordination compounds is likely to be colored?
Solution:
The complex [Cu(NH3)4]2+ contains a transition metal with d-electrons that can be excited, resulting in color.
Steps: 6
Show Steps
Step 1: Identify the coordination compounds given in the question.
Step 2: Look for the presence of transition metals in the compounds.
Step 3: Check if the transition metal has d-electrons (these are electrons in the d-orbitals).
Step 4: Understand that d-electrons can be excited to higher energy levels when light hits the compound.
Step 5: Realize that when d-electrons are excited, the compound can absorb certain wavelengths of light, leading to color.
Step 6: Conclude that the complex [Cu(NH3)4]2+ is likely to be colored because it contains copper (Cu), a transition metal with d-electrons.
