Problem: What is the most electronegative element in this molecule? H3C-B-CH2-Br-CH3

FREE Expert Solution

Electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself

Recall that the most electronegative element is fluorine (F) while the least electronegative element is francium (Fr).


This means the trend for electronegativity is as follows: it increases from left to right and decreases down a period in the periodic table. 


The given elements are:

H3C-B-CH2-Br-CH3
