A molecular modeling kit is to be given to build a model of trans-1, 3-dimethylcyclohexane so that it looks exactly like the given chair conformation. Concept introduction: In the case of disubstituted cyclohexane, the relationship between these two substituents with the ring is explained with the help of a Haworth projection. Since cyclohexane ring undergoes chair flipping with no switching of either substituent from their side, the relationship between these substituents on a cyclohexane ring does not change on flipping, that is, the cis substituents remain cis, and trans remain trans on flipping. In a Haworth projection, the ring is depicted as being planar, and bonds to substituents are drawn perpendicular to that plane in such way that these substituents come in the plane of the ring, and one side of the ring will be either above this plane or below this plane, depending on the rotation around the plane.

5. Compressibility (6 points total). The isothermal compressibility is a measure of how hard/easy it is to compress an object (how squishy is it?) at constant temperature. It is др defined as Br=-()=-(200²)T' (a) You might wonder why there is a negative sign in this formula. What does it mean when this quantity is positive and what does it mean when this quantity is negative? (b) Derive the formula for the isothermal compressibility of an ideal gas (it is very simple!) (c) Explain under what conditions for the ideal gas the compressibility is higher or lower, and why that makes sense.

19. (3 pts) in Chapter 7 we will see a reaction of halocyclohexanes that requires that the halogen occupy an axial position with this in mind, would you expect cis-1-bromo-3-methylcyclohexane or trans-1-bromo-3-methylcyclohexane to be more reactive in this reaction? Briefly explain your choice using structures to support your answer. Mere-eries-cecleone) The tran-i-browse-3-methylcyclohexione
