This video specifically showed the nucleophilic attack effect which refers to the process in which a nucleophile, which is an electron-rich species, donates a pair of electrons to an electron-deficient site, typically a positively charged or partially positive atom (an electrophile). This interaction is fundamental to many reaction mechanisms, particularly substitution and addition reactions.
Each reaction video moving forward shows and explains these concepts inside the mechanism.
For example if the next reaction you cover is substitution (SN1 and SN2) reactions then you'll see that explained in these videos:
This is E2 because of the bulky base, tertoxide OC(CH3)3, this specific base is only used in E2 reactions. The overall reason for this is because that base is way too hindered to complete an SN2 reaction. You'll see this explained with examples in the E2 Lesson video below at timestamps 01:34 (SN2 vs E2) and 10:42 (Anti-Zaitsev).
