MLNVILI SYNTHESIS OF 2-BUTOXYNAPHTHALENE OH 1. NaOH, ETOH 2. n-BuBr DISCUSSION: Nucleophilic substitution reaction is a frequently used method to convert one functional group into another. A nucleophile is mixed with an electrophile and the nucleophile replaces the leaving group to produce a new compound. In this experiment, a weak nucleophile (2-naphthol) is converted into a strong nucleophile. Then this...

We performed a synthesis of methyl diantilis lab. The first step
involved a Sodium Borohydride Reduction of
3-Ethoxy-4-hydroxybenzaldehyde (Ethylvanillin) shown below.
The next step of the experiment involved Etherification of
3-ethoxy-4-hydroxylbenzyl Alcohol using one of four alcohols
(methanol, ethanol, 1-propanol, or 2-propanol). The alcohol I used
was methanol. The reaction is predicted below.
Below is the NMR sample for my product with the integration and
ppm for each peak displayed.
Based on this information, answer the following questions.
