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.

Deprotonation of α carbon

Attach of enolate ion with the aldehyde (nucleophilic attack)

Protonation of the alkoxide ion to give aldol product

Dehydration of the aldol addition product to form conjugated enone (aldol condensation product)

Please note that aldol condensation product is formed at higher temperature.

Note : Simple way to enter aldol condensation product instead of writing the entire mechanism is to remove the two α hydrogens from one carbonyl molecule and oxygen from another carbonyl molecule. Form a double bond between the carbon atoms as shown in scheme below,

To draw : The aldol condensation product formed when the compound given is heated in presence of aqueous sodium hydroxide.
