4. Purification of the diphenylacetylene product obtained from Part B involves the addition of awater:methanol mixture to the reaction mixture (step d), followed by filtration and washing withwater (step e). Explain how these steps allow for the purification of the product. Be sure to outlinewhat starting material(s) or reagents is/are being removed in each step.

Draw the structural formula(s) for the major product(s) of each of the following reactions. Unless required, ignore stereochemical details. Only questions (h.),(I.),(j.)
The conversion of alcohols into alkyl halides by reaction with hydrogen halides is an example of a Nucleophilic Substitution Reaction. This kind of reaction can proceed by two different mechanisms depending on the structure of alcohol substrates used. Generally, primary alcohols are substituted via SN2 mechanism, while secondary and tertiary alcohols undergo SN1 mechanism. Consider the following reaction given in the picture below and the questions in the picture too.
An organic chemistry experiment involves a nucleophilic substitution (SN2) reaction using 1-iodobutane and 2-naphthoxide ion. The 2-naphthoxide ion is generated from 2-naphthol and sodium hydroxide in an ethanol solvent. The experiment includes steps like generating the nucleophile, conducting the SN2 reaction, and analyzing the product using 1H NMR spectroscopy. Question: Write the structure of the undesired side product if CH3CH2O‾ (ethoxide) reacts with 1-iodobutane.
