2. Three samples labelled R, S, and T possess identical melting points: ~99 °C. When a 75/25 mixture of S and T is prepared, its melting point is 90-95 °C. The melting point of a 50/50 mixture R and T is 79-91 °C. The mp. of a 25/75 mixture of R and S is 97-98 °C. What information does this does this tell you about identity of the 3 compounds? (ie. Which compounds are the same, and which compounds are different? Use only the information you have learned from the slides and your lab manual.) Wht would you expect as a melting range for a 75/25 mixture of R and T?

1. Is this molecule is saturated? Explain your reasoning. нннн Н-с—С—С-с-н H HHH
An aldehyde has a boiling point] that is intermediate between an alkane (of the same mass) and an alcohol (also of the same mass). Why is this? Group of answer choices The aldehyde's mass is intermediate between the alcohol and the alkane. The aldehyde molecules interact with each other through dipole/dipole interactions, which are stronger than the interactions between alkane molecules and weaker than the interactions between alcohol molecules. there is no known explanation for the intermediate boiling points of aldehydes. None of the above.
