Bromine is more electronegative than carbon and so the bond is polarised in the way that we have already described with C-F and C-Cl. The polarity of the carbon-halogen bonds is important in the reactions of the halogenoalkanes.Fluorine is assinged the oxidation number of -1 because it attracts the electrons in the bond more strongly than the carbon does. Thus, fluorine appears to have an extra electron, -1 oxidation number. F is the most electronegative element on the periodic table.

Is the most electronegative element in the periodic table a BR B F C Cl D I?
* As fluorine has the highest attraction for the shared pair of electrons in a covalent bond with any other element because of its small atomic radius and large nuclear charge, it is the most electronegative element in the modern periodic table.

Who is more en C or N?
It is obvious that an element with more electrons in valence shell would try to pull the electrons with more force in a bond, as compared to that element, which has less nuclear attractive force. From all this, we conclude that Nitrogen is more electronegative than carbon.
Is BR more electronegative than Cl?
Atomic chlorine is much more electronegative than atomic bromine, which is more electronegative than atomic iodine. So if Cl2 is combined with Br– , a reaction will occur because a chlorine atom wants electrons much more than bromide wants to keep its extra electron.
Why is Cl more electronegative than Br?
Although the bromine nucleus is more positively charged than the chlorine nucleus, the increase in the radius and the extra shielding in the bromine atom outweigh this factor, which means that an electron is more easily attracted into the outer shell of a chlorine atom than that of a bromine atom, so chlorine is more …

Which is more electronegative Cl or N?
Chlorine is more electronegative than nitrogen. Electronegativity is the tendency of an element to attract the bond pair electron towards itself. From left to right of the periodic table the electronegativity increases, due to increase in effective nuclear charge.
How do you find electronegativity values?
To calculate electronegativity, start by going online to find an electronegativity table. You can then assess the quality of a bond between 2 atoms by looking up their electronegativities on the table and subtracting the smaller one from the larger one. If the difference is less than 0.5, the bond is nonpolar covalent.
What is the correct order of electronegativity among the following options?
The order of electronegativity is F>O>Cl>Br>S>I>C>P>H.

Which is the second most electronegative element?
Oxygen is second most electronegative because its needs only 2 electrons to complete its octet.
Why are halogens more electronegative than carbon?
Answer. This is because thier valency is less than that of carbon. Thus, they have more combining capacity.
