Whether the maximum number of carbon atoms for water-soluble aldehydes will be greater than or less than that for water-soluble alcohols is to be determined. Concept introduction: Solubility depends on the nature of intermolecular forces (IMFs) in the solute and solvent. If both have the same type of IMFs, the solubility is high. Polar compounds dissolve in polar solvents, while nonpolar compounds dissolve better in nonpolar solvents. In compounds that contain both polar and nonpolar groups, the number of carbon atoms in the nonpolar part influences solubility. In a given class of compounds, the polar part of the molecule is fixed, so the solubility in polar solvents decreases as the length of the nonpolar (alkyl group) part of the compound increases. In case of two types of compounds with different polar groups but same alkyl group, the solubility depends on the nature of the polar group.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

Draw and show the full mechanism of how the molecule ((1E, 3E, 5E)-1-methoxyhepta-1,3,5-triene) is built using substitution and elimination reactions. You can start with an alkane of any carbon length with any number of leaving groups attached or with a alkoxide of any carbon length (conjugate base of an alcohol). Show each step and and explanation for each reaction. Also include why the reagents and solvents were picked and what other products can be expected.
