Step 1
Determine boiling point for compound Z
Answer
To determine the boiling point of compound Z, we can analyze the data for compounds X and Y. Both compounds have the same molecular weight of 60, but differ in their boiling points.
Compound X, with a straightforward alkane structure, has a boiling point of 97°C. Compound Y, having an alcohol functional group, has a higher boiling point due to hydrogen bonding, at 118°C.
Given that compound Z appears to have a structure similar to compound Y with functional groups potentially affecting its boiling point, and considering the trend in boiling points, we can infer that:
The boiling point of compound Z is likely between 97°C and 118°C, estimating it around 110°C. The strong hydrogen interactions in compound Y suggest a close relationship, and thus an educated guess for compound Z could be approximately 110°C.
