The structure of the alkyl bromides used in a malonic ester synthesis of ethyl 2-methyl-4-pentenoate.
Ethyl 2-methyl-4-pentenoate by Malonic ester synthesis.
The alkylation of diethyl malonate or a related ester of malonic acid at the carbon alpha (immediately next) to both carbonyl groups, followed by conversion to a substituted acetic acid, characterizes the chemical reaction known as the malonic ester synthesis.
As a result, it is evident from the structure of ethyl 2-methyl-4-pentenoate that ethyl and methyl bromides are the alkyl bromides employed.

<span>In this item, we are asked to calculate for the mass of 22.05 mole of octane given that its molecular mass is equal to 114.22 g/mol. To answer this item, we simply have to multiply the number of moles with the molecular mass. That is, (114.22 g/mol)(22.05 mol) which is equal to 2518.221 grams. </span>
Lattice energy = -820 kJ/mole
Heat of solution = +22.6 KJ/mole
Lattice breakdown is and endothermic reaction during the
formation of solution
And hydration is an exothermic reaction as ions interact
with solvent molecules
By using the formula,
Enthalpy of solution = Lattice energy + hydration energy
Now put the values and calculate,
+22.6 kj/mole = + 820 kj/mole + hydration energy
Hydration energy = 22.6 Kj/mole – 820 Kj/mole
Hydration energy= -797.4 Kj/mole
It's defined as the salt concentration in sea water. Ex: Sodium and Chlorure
