1,2-Dibromoethane, also known as ethylene dibromide (EDB), is an organobromine compound with the chemical formula C 2 H 4 Br 2.Although trace amounts occur naturally in the ocean, where it is formed probably by algae and kelp, it is mainly synthetic.It is a dense colorless liquid with a faint sweet odor, detectable at 10 ppm, is a widely used and sometimes-controversial fumigant. Therefore, the covalent bond H-Br generates polarity across it. But replacing one I atom in the purple solid I 2 with another nonmetal also makes a significant difference. Whereas the other atom whose electronegativity is lesser gains partial positive charge. It has its great use in the preparation of sanitizer and many disinfectants. Phosphorus Tribromide PBr3 6. Answer = AsH3 ( Arsine ) is Polar What is polar and non-polar? The greater the dipole moment of a molecule, the more is the polarity of that molecule. However, in the case of HBr, the shape of this molecule is linear because the molecules formed with two atoms form a linear-shaped molecule.

The HBr molecule is made up of hydrogen and bromine atoms that differ in their electronegativity. It means the charge distribution on both atoms is uniform. It also dissociates readily in water. The density of the HBr molecule is around 1.49 g/cm³. Polar molecules interact through dipole–dipole intermolecular forces and hydrogen bonds. This chemical compound is mainly used for making inorganic and organic bromine compounds. These atoms are attracted to each other due to electrostatic forces between them. [More than one answer is possible.] The melting point of HBr is −86.9 °C or −124.4 °F. Lattice energy increases as the charge increases; lattice energy decreases as the size of the ions increases KBr < KCl < LiCl < CaO 8. HI is a colorless gas, and reacts with NaOH to give sodium iodide (used in iodized salt). It is widely used as a catalyst and as a reagent in a large number of organic reactions. Bromine has a higher electronegativity than hydrogen due to which electron bonded pair gets attracted slightly more towards bromine atom making HBr a polar molecule and results in a net dipole moment.

Each atom in HCl requires one more electron to form an inert gas electron configuration. Save my name, email, and website in this browser for the next time I comment. The covalent bond is formed between two atoms when they share the electrons of each other to get stabilized. The HBr molecule is prepared by a variety of methods in the laboratory by the process of distillation of a solution of potassium bromide in the presence of sulphuric acid. The observed dipole moment of the HBr molecule is around 2.6×10 −30Cm. As a result, the bromine atom gains a relatively negative charge on it and the hydrogen atom gains a positive charge. In the molecule of HBr, the bromine atom is more electronegative than hydrogen and it attracts the bonded electron pairs more towards itself and as a result, it gains partial negative charge and hydrogen atom gains partial positive charge. In a hydrogen bromide molecule, the unequal charge distribution between both atoms occur. Polar Covalent Compounds. In case, if the atoms that are covalently bonded have different values of electronegativity.

Whereas the nonpolar molecule is symmetrical in shape and has a zero dipole moment. Below is the geometrical structure of the HBr molecule. The more electronegative atom attracts the bonded electron pair more towards itself and as a result, the atom gains partial negative charge whereas other atom gains partial positive charge. A molecule may be nonpolar either when there is an equal sharing of electrons between the two atoms of a diatomic molecule or because of the symmetrical arrangement of polar bonds in a more complex molecule. Question: Is H2SO3 an ionic or Molecular bond ? The more the electronegativity of an atom, the more strongly it can attract the electrons. And the molecules that are nonpolar have their zero dipole moment. you can check out the reason for the polarity of Ammonia. Basically, electronegativity can be defined as the strength of an atom how strongly it can attract the bonded pair of electrons. These are discussed as below. The covalent bond in which both connected atoms have equal electronegativity share equal charge. Due to this unequal charge distribution, the polarity in the HBr molecule is developed and it results in a non zero dipole moment value. The calculated boiling point of HBr is around −66.8 °C or −88.2 °F. A polar covalent bond exists when atoms with different electronegativities share electrons in a covalent bond. The polarity of a molecule is also directly proportional to its dipole moment. It means the bromine atom share a greater portion of bonded electrons.
