Yes, since the Williamson Ether Synthesis proceeds via an SN2 mechanism, the nucleophile will indeed perform a backside attack on the electrophile (typically a primary alkyl halide or tosylate).

Thank you for letting us know, we will fix this 👍

You'll find the chart with the electron and molecular geometry tables as a downloadable pdf under the description of the video. We don't have downloadable lecture slides at this time due to copyright reasons but we are looking into ways to add more downloads on videos. For now we are adding important templates and charts as downloads and you'll find our practice exams and study with us series with downloadable pdfs. 

Thank you for your feedback, we appreciate it!
