The electronegativity of bromine is larger than hydrogen, which shifts the location of shared electrons toward bromine.

Why is hydrogen chloride polar covalent?
Hydrogen chloride (HCl) is a polar covalent molecule because it has a significant difference in electronegativity between the hydrogen and chlorine atoms. Chlorine is more electronegative, meaning it has a stronger attraction for electrons, causing the shared electron pair between hydrogen and chlorine to be unequally shared. As a result, the chlorine atom acquires a partial negative charge, while the hydrogen atom acquires a partial positive charge. This uneven distribution of charge creates a dipole moment, making HCl a polar covalent molecule.
Why is the boiling point of water high compared to hydrogen chloride?
Water and hydrogen chloride are both polar compounds (which is to say, the molecule has both positive and negative poles) but water is more polar than hydrogen chloride. Oxygen has a higher electronegativity than chlorine does, and consequently, there is a greater difference in electronegativity between oxygen and hydrogen than there is between chlorine and hydrogen. Consequently, there is a greater concentration of electrons at the oxygen atom than at the chlorine atom in these two molecules. Polarity then leads to attraction between molecules (which align themselves so that negative poles can attract positive poles) and greater attraction between molecules will result in a higher boiling point.
What is the charge associated with each side of the HCl molecule?
HCl has a single bond in between hydrogen and chlorine. Hydrogen's one and only electron is tied up in that bond. Chlorine's other 6 valence electrons are on that side due to chlorine's high electronegativity. So, the chlorine side will be negative and the hydrogen side will be positive. This makes HCl a highly polar molecule.
Why Hcl molecule is polar?
Because hydrogen and chlorine have a difference of electronegativity 0.9, chlorine is more electronegative so shared electron pair is more closer to chlorine and it acquires partially negative charge.
How does sodium atom and a chloride atom combine?
A sodium atom has one electron outside a closed shell, and a chlorine atom lacks one electron to fill a shell. A sodium chloride molecule forms by ionic bonding, the ionization of sodium and chlorine atoms and the attraction of the resulting positive and negative ions.
Why is hydrogen chloride polar?
Hydrogen chloride is non polar because in molecules such as (hcl) the electron pair of bond is pulled closer to more electroneative chlorine atom.As a result of this the chlorine atom develops a tiny negative charge,where as the hydrogen atom develops a tiny positive charge.The hydrogen chloride molecule has a slight separation of charge within it and describe as a polar molecule
Why does Hydrogen Chloride not conduct electricity when dissolved in hexane but conducts electicity when dissolved in water?
Water is a polar molecule and hexane is non-polar. This means that water has positive charges that grab on to the negative-chlorine and water has negative charges that grab onto the positive-hydrogen. This pulls the hydrogen and chlorine apart as positive and negative ions. The these positive and negative ions can move around separately as positive and negative electrical carriers. In hexane the hydrogen and chlorine are locked together, a single neutral molecule and no charged ions. Any positive movement of the hydrogen is locked to the negative movement of the chlorine, so any movement balances out to zero charge movement and zero electrical movement.

Why Hcl molecule is polar?
Because hydrogen and chlorine have a difference of electronegativity 0.9, chlorine is more electronegative so shared electron pair is more closer to chlorine and it acquires partially negative charge.
Is chlorine positives or negative?
The atom is neutral; the ion chloride is negative.
What is the charge on the chlorine atom in the molecule hcl?
Chlorine gains an electron and becomes negative 1 charge. Hydrogen donates an electron so becomes positive 1 charge.
What happens when chlorine gains an extra electron on the outer shell?
It becomes a negative ion.
How does sodium atom and a chloride atom combine?
A sodium atom has one electron outside a closed shell, and a chlorine atom lacks one electron to fill a shell. A sodium chloride molecule forms by ionic bonding, the ionization of sodium and chlorine atoms and the attraction of the resulting positive and negative ions.
What does is chloride?
Chloride or Cl- is the anion (Negative ion) formed by a single chlorine atom that gains an extra electron.
Can a positively charge hydrogen ends of water molecules attract chloride ions?
chloride ions have a negative charge... hydrogen ions have a positive charge... positive and negative means attraction
