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.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.Electronegativity decreases in a group on going from top to bottom. Therefore increasing electronegativity order is I < Br < Cl < F.

Is BR more electronegative than I?
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.

Is BR the most electronegative?
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.
Which is more electronegative F Cl Br or I?
Electronegativity decreases in a group on going from top to bottom. Therefore increasing electronegativity order is I < Br < Cl < F.
Why is iodine less reactive than bromine?
Iodine has 5 shells whereas bromine has 4 shells. Since bromine has less number of shells, the outer shell is closer to the nucleus and there is a strong force of attraction between the positive charge of the nucleus and the electrons in the outermost shell.

Electronegativity
If the electrons of a bond are more attracted to one of the atoms (because it is more electronegative), the electrons will be unequally shared.

Which has more electronegativity?
Fluorine is the most electronegative element on the periodic table. Its electronegativity value is 3.98. Cesium is the least electronegative element. Its electronegativity value is 0.79.
How do you know which element is more electronegative?
On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group. As a result, the most electronegative elements are found on the top right of the periodic table, while the least electronegative elements are found on the bottom left.

How do you determine electronegativity?
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 electronegativity of B?
Is F or Br more reactive?
Among the halogens, fluorine, chlorine, bromine, and iodine, fluorine is the most reactive one.
Is Br or F more stable?
Bromine being in between lacks both these characteristics. Thus, the stability of oxides of halogens decreases in the order : I > Cl > Br > F.
Which of the following has greater electronegativity a FB Cl C Br d n?
Answer. Answer: Thus, fluorine is the most electronegative element, while francium is one of the least electronegative.
What is more reactive bromine or iodine?
The order of reactivity is: chlorine > bromine > iodine. This is because chlorine could displace bromine and iodine, bromine could only displace iodine, but iodine could not displace chlorine or bromine.
Is bromine more reactive than iodine?
The reactivity of the halogens decreases down the group. Therefore, chlorine is more reactive than bromine and bromine is more reactive than iodine.

Why is I2 less reactive?
I2 is less reactive than ICl as I−I bond is stronger than I−Cl bond.
