Solid Co2(CO)8 shows infrared CO stretching bands at 1857, 1886, 2001, 2031, 2044, 2059, 2071 and 2112 cm–1. When Co2(CO)8 is dissolved in hexane, the carbonyl bands at 1857 and 1886 cm–1 disappear. These changes in the infrared spectrum in hexane are due to:
- a)Loss of terminal CO
- b)Structural change of Co2(CO)8 involving conversion of terminal CO to bridging CO
- c)Dissociation of Co2(CO)8 to Co(CO)4
- d)Structural changes of Co2(CO)8 involving conversion of bridging CO to terminal CO
Correct answer is option 'D'. Can you explain this answer?

Solid Co2(CO)8 shows infrared CO stretching bands at 1857, 1886, 2001,...
Explanation:
When Co2(CO)8 is dissolved in hexane, the carbonyl bands at 1857 and 1886 cm1 disappear. This suggests that there is a structural change in Co2(CO)8 in hexane solution.
The possible reasons for this change are:
a) Loss of terminal CO: If terminal CO is lost, there should be a decrease in the number of CO stretching bands. However, in this case, the number of CO stretching bands remains the same.
b) Structural change of Co2(CO)8 involving conversion of terminal CO to bridging CO: If terminal CO is converted to bridging CO, there should be a decrease in the number of terminal CO stretching bands and an increase in the number of bridging CO stretching bands. However, in this case, the number of CO stretching bands remains the same.
c) Dissociation of Co2(CO)8 to Co(CO)4: If Co2(CO)8 dissociates to Co(CO)4, there should be a decrease in the number of CO stretching bands. However, in this case, the number of CO stretching bands remains the same.
d) Structural changes of Co2(CO)8 involving conversion of bridging CO to terminal CO: If bridging CO is converted to terminal CO, there should be an increase in the number of terminal CO stretching bands and a decrease in the number of bridging CO stretching bands. This is consistent with the observation that the carbonyl bands at 1857 and 1886 cm1 disappear in hexane, which suggests that some of the bridging CO groups have been converted to terminal CO groups.
Therefore, the correct answer is option 'D', which suggests that there is a structural change in Co2(CO)8 involving the conversion of bridging CO to terminal CO.

Solid Co2(CO)8 shows infrared CO stretching bands at 1857, 1886, 2001,...
As 1857 cm-1 is characteristic starching frequency of bridge CO so as it disappeared it is expected that it changes to terminal CO group
