What a great start to our Electrophiles and Nucleophiles page! YEAH
OK. Just 2 big ideas to take note here.
1) ELECTROPHILES are POSITIVELY charged
2) NUCLEOPHILES are NEGATIVELY charged
so now… what makes so many reactions happen with them around?
we shall take a look at their collaborators in such reactions!
Prime targets for electrophiles are…
the humble C=C alkene functional group is an amazingly good magnet that attracts ELECTROPHILES like mmm… raindrops to the ground!
It can do so… because the C=C double bond comes packed with electrons jammed within the confines of the 2 adjacent carbons! Just like how a relatively OK looking slice of watermelon contain large volumes of fruit juices!”
The Negative charge of so many close-by electrons draw electrophiles to come closer to say a friendly “hi” or “cheerios”! And it results in a very amicable covalent bond union between our prince charming Electrophile and Sweetie-pie ALKENE in a reaction we call “ELECTROPHILLIC ADDITION” because electrophiles and their alkene partners react to form just one single product!
