From me l think the carbon has a slight negative charge due to the carbon which is slightly positive , so the hydrogen bonded to it will become slightly positive , which then is attacked by the nucleophile OH
There are many factors that determine the true strength of a bond (electronegativity (polarity)), size of atoms, orbital overlap, etc). Meaning, very polar bonds (like C-F) can also be very strong (because the bond has a short bond length). This is covered a little bit at 05:38 in this video - ua-cam.com/video/hri0ig1nW3M/v-deo.html In general however, during organic reactions and mechanisms it is polar bonds that are more likely to react and undergo changes in a reactant. This is because electrophiles are attracted to electron rich regions and nucleophiles electron deficient regions, without polarity and differences in electronegativities - these regions wouldn't exist. It is important to realise that bond polarity isn't the only thing that will determine how a molecule reacts however - steric hindrance, resonance effects, and the presence of other functional groups can also play crucial roles in determining reaction pathways. In summary then - bond polarity isn't the only thing that influences bond strength. However in general, for organic chemistry (the point of this video), the greater the polarity of the bond, the more likely it is to be attacked by a nucleophile or electrophile. That is what I mean in the video. Hope that helps :)
Sirrr, pls reply .If the greater the polarity the weaker the bond , then surely carbon fluorine being very polar is the weakest and carbon iodine is the strongest? I am kind of mixed up pls clarify .thank u sm .i love ur videos .
Thank you for the message! Great question. There are many factors that determine the true strength of a bond (electronegativity (polarity)), size of atoms, orbital overlap, etc).

Another great video .
Thank you very much!! You've made it super clear, and the recap at the beginning was perfect, as I did need a refresh of those basic concepts :).
Thank you! Glad it helped :)

Thanks well explained
Thank you! Hope it helped :)
sir why the carbon next to the carbon connected to halogen?
It comes from a reaction Process called halogenation
From me l think the carbon has a slight negative charge due to the carbon which is slightly positive , so the hydrogen bonded to it will become slightly positive , which then is attacked by the nucleophile OH
U said the greater the polarity the weaker the bond but my teacher said the greater the polarity the stronger the bond. Which is correct?
