What type of bond is Br Cl?

Polar Covalent
The bond between BrCl is Polar Covalent with negative end on Cl. This bond arises due to electronegativity difference between bromine and chlorine.

What is the electronegativity of Cl and Br?

Electronegativity (Pauling scale)

What is the polarity of Cl?

The electronegativity of the chlorine atom is 3.16. Due to equal charge distribution on both atoms, there exists no polarity across the molecule.

How is the polarity of BrCl determined?

Polarity is decided by the difference in the electronegativity values of the atoms. The difference between the different atoms is .2, you should do the calculation yourself to verify. Gerry St-Aubin, former High School Chemistry/Biology/Science Teacher. BrCl is a polar molecule.

Which is weaker the Br-Br bond or the Cl-Cl bond?

In this case, the bond energy is +193 kJ mol-1. That means that the Br-Br bond is weaker than the Cl-Cl bond. If the atoms are different at each end of the bond, it works in exactly the same way. For example, the bond energy of the H-Cl bond is +431 kJ mol-1, and is given by the equation:

How are the bonds of CCL 4 polar?

For example, the four bonds in a molecule of CCl 4 are significantly polar, but they are symmetrically arranged around the central carbon atom. No side of the molecule has more negative or positive charge than another side, and so the molecule is non-polar.

What does this mean for polar bond reactivity?

A polar bond is one in which two atoms of unequal electronegativity share a pair of electrons. The electrons are pulled towards the atom with the greater electronegativity. That leaves the more electronegative atom slightly negatively charged and the less electronegative one slightly positively charged. What does all this mean for bond reactivity?
