This question is about inorganic Chemistry regarding CO
stretching and Group Theory.
Cobalt tetracarbonyl hydride, HCo(CO)_4, is an important industrial catalyst for the production of aldehydes from alkenes, carbon monoxide, and hydrogen gas via a process called hydroformylation. The compound is a low boiling liquid, which makes structural characterization difficult. Two possible structures are shown below. Predict the number of CO stretching frequencies expected in the IR and Raman spectrum for both structures. Which structure is the correct structure based...

Analyze each pair of compounds structures represent. Your cho cach pair of compounds below. Identify which class of isomers each pair of s represent. Your choices are: (i) constitutional, (ii) conformational, (iii) omers, (iv) diastereomer or (v) identical (non-isomers). Only one label for each pair should be used. For each case show work (drawings, (R)/(S), rotation of bonds, chair- "ps, etc) which led you to each answer for the pairs below. Any differences of answers between you and your peers...
