Why is ch3br an electrophile
Recognizing Electrophiles and Acids. Electrophiles accept electrons into their lowest unoccupied MO. • a partial positive charge revealed via resonance contributor(s) • a weak bond usually involving a pair of heteroatoms e.g., X-Y bonds like Br-Br O CH3 H3C O. Cl Cl.You can write a book review and share your experiences. Other readers will always be interested in your opinion of the books you've read. Whether you've loved the book or not, if you give your honest and detailed thoughts then people will find new books that are right for them. The pull of electrons in the polar bond between the carbon and chlorine cause a charge distribution between the two atoms based on electronegative effects. The carbon gains a partial positive charge and the chlorine gains a partial negative charge. The positively charged carbon in this case would be the electrophile.

Directing Effects CH3 is an ortho/para director Why? Arenium ion stability CH3 stabilizes adjacent carbocation by electron-donating inductive effect Extension: Any carbocation stabilizing group = ortho/para director Ortho/para directors...Dec 04, 2015 · Pretty much never. A nucleophile MUST be a Lewis base, and there is a very poor chance that "HBr" will donate electrons BEFORE it donates its proton; its pKa is about -9, i.e. it's a pretty strong acid. It is much, much more likely to give up a proton by accepting electrons. That just shows that it is a Lewis acid, NOT a Lewis base, and therefore it is an electrophile.
