Also add the other product notice how the Tema s can be converted to this by use of a strong base such as sodium a sodium ion (Na) is not drawn, in this case it is just a spectatorio PCW27 - Mechanistic steps - Part Name: Time spent 2) Label the above compounds with the appropriate name from the previous...
OH 1-Butyne Acetaldehyde Alkyne anions react with the carbonyl groups of aldehydes and ketones to form alkyayl alcohols. The reaction mechanism between 1-butyne and acetaldehyde includes the following steps: 1. Sodium amide deprotonates the terminal alkyne 2. The alkyne anion acts as a nucleophile and adds to the aldehyde carbonyl: 3. Proton transfer from solvent forms the product alcohol. Diagram the mechanism on a separate sheet of paper, and then draw the structure of the product(s) of step 2. ....

Complete the following reaction by drawing the structure of the major product(s) expected. You do not have to consider stereochemistry. You do not have to explicitly draw H atoms. If there is more than one major product possible, draw all of them. Separate multiple products using the + sign from the drop-down menu.
