Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Hello Student we should know first how to dissociate neutral molecule to ions, if we dissociate NaOH you will get Na+ and OH- now you will get question why Na is + and OH is minus reason for this is electronegativity of that ion now you can check electronegativity of sodium is 0.93 and electronegativity of oxygen is 3.4 so what is now electronegativity means- electronegativity means how strongly atom attracts electron to themselves that is why OH ions having more electron because that I am having more electronegativity which came from bond of NaOH. and OH having minus charge because it having more electronegativity, that is why bond between sodium and hydroxy shift towards hydroxyl group and hydroxide become nucleophile as well as we can call it as electron rich. and sodium plus become electrophile because it having less electron in its outermost shell, so it has positive charge. main concept to identify electron density on neutral atom is electronegativity if you you are able to check electronegativity then you can find out the electron density. thank you for asking this question if you have any doubt you can ask
so both electrophile and neucleophile are present in reagent
why we call naoh is electrone rich reagent if both electroohile and neucleophile are present in naoh so we must say nuetral thier is no density difference
because hydroxy is stronger nucleophile than sodium electrophile. nucleophile dominance on electrophile so it acts as nucleophile
as well as electronegativity difference is bigger so nucleophile is more stronger than electrophile so it is called as nucleophilic reagent
ok thank you
i am confused in hcl why hcl is electroohile while cl is more electronegative than h
