In this case, the hydrogen in the -COOH group has been replaced by an ethyl group. The attractions that form between the ethanol and water molecules are also hydrogen bonds (Figure below). Notable At 20C, for example, 177 g of NaI, 91.2 g of NaBr, 35.9 g of NaCl, and only 4.1 g of NaF dissolve in 100 g of water. The "ethanoate" bit comes from ethanoic acid. we have to analyse the spectral data, Q:Show how you would carry out each of the following transformations Menu. 1) Iodine, being a non-polar substance, should dissolve the most in nonpolar solvents. The new attractions formed between the ions and hexane would be considerably weaker than the attractions broken, making the solution process significantly endothermic. Hexane will be least soluble.
