How can water have polar bonds and be a polar molecule too?
In water, the two hydrogen's are bonded to the one oxygen. The differing electronegativities make the electrons become shared unevenly. They then become charged positively towards the Hydrogen's (because of less electronegativity) and oxygen charged negatively. This is what makes the bonds polar. The bent shape of the whole molecule makes it so there is more overall negative charge towards the oxygen (because the electrons get attracted more towards the atom with greater electronegativity). This is what makes the molecule polar.
Does the chlorine atoms in hydrogen chloride have a stronger attraction for the electrons than the hydrogen atoms do?
Yes, the chlorine atom in hydrogen chloride has a stronger attraction for electrons compared to the hydrogen atom. This is because chlorine is more electronegative than hydrogen, meaning it has a greater tendency to attract electrons towards itself. This results in a polar covalent bond in which the electron pair is more strongly attracted to the chlorine atom.
Why dont hydrogen and oxygen atoms share electrons equally in a water molecule?
Because the electronegativity of oxygen is about 3.5 and the electronegativity of hydrogen is about 2.5. So, the electrons shared in this polar covalent bond spend more time in the orbitals around oxygen that the orbitals around hydrogen giving the molecule slightly negative and positive ends.
How is water molecule polar?
water molecule is polar due to higher electronegativity of the oxygen atom than hydrogen. The oxygen molecule pulls the shared pair of electrons partially towards itself resulting in the hydrogen atom having a small positive charge on it and the oxygen atom having a small negative charge, thus causing polarity.
When NaCl is dissolved in water negative end of the water molecules is attracted towards what?
Ion-dipole attraction dictates that the negative pole of a water molecule will be attracted to the sodium cation and the positive pole of a water molecule will be attracted to the chloride anion.

A hydrogen bond forms when a positively charged hydrogen ion bonds to a negatively charged atom?
No, hydrogen bonding occurs in covalent compounds in which hydrogen is bonded to nitrogen, oxygen, or fluorine. These elements will pull electrons towards them getting a partial negative charge and giving hydrogen a partial positive charge.The actual hydrogen bonding occurs when the partial positive charge on one such molecule is attracted to the partial negative charge on another.Technically it isn't a type of bond.
When are hydrogen bonds formed?
Short Answer: a partially positive hydrogen atom gets attracted to a partially negatively charged atom. _______________________ Take water for example. There is an Oxygen atom (which pulls electrons towards it-- making it partially negative) There are also two hydrogen atoms. The (negatively charged) electron on each H atom is being pulled towards the O atom, making the Hydrogen partially positive. Now, when two water molecules come together, the partially positively charged H's on one water molecule are attracted to the partially negatively charged O's on the other molecule. This attraction between oppositely charged atoms on different molecules creates a 'hydrogen bond'.
Water is a polar molecule because the oxygen end acts charged and the hydrogen end acts charged?
Oxygen is more electronegative than hydrogen, meaning that it likes to pull electrons towards itself more than hydrogen does. Since oxygen likes 2 electrons, it will bond to 2 hydrogen atoms, pulling 1 electron towards itself from each hydrogen. This produces a partial positive charge on the hydrogen and a partial negative charge on the oxygen. The answer is D (in english)
What are the partial charges in a water molecule?
The Oxygen molecule and Hydrogen molecules have different electronegativity (due to position on Periodic Table). As Oxygen is more electronegative it draws the negatively charged electrons towards itself. This makes the hydrogen atoms more positive and hence the partial charges.
Why dont hydrogen and oxygen atoms share electrons equally in a water molecule?
Because the electronegativity of oxygen is about 3.5 and the electronegativity of hydrogen is about 2.5. So, the electrons shared in this polar covalent bond spend more time in the orbitals around oxygen that the orbitals around hydrogen giving the molecule slightly negative and positive ends.
What reactant for the reaction that is powered by the sun hitting photosynthesis ll?
First of all it's not photosynthesis II, its photosystem II. well basically, the hydrogen atom within the water molecule loses its electrons and the electrons basically travels through all the photosytems via electron transport chains, towards the NADP Reductase where NADP+ is attached with the electrons from the hydrogen atoms of the water molecule to form NADPH
Polar molecules they attrack to other substances?
Polar molecules have unequal distribution of electrons. Water for example, oxygen is more electronegative than hydrogen so it will pull electrons towards itself, giving oxygen partial negative charge on it and partial positive charge on the hydrogen. A hydrogen bond forms between the partial negative charge on oxygen on another water molecule and partial positive charge on hydrogen on other water molecule.

water molecule is polar due to higher electronegativity of the oxygen atom than hydrogen. The oxygen molecule pulls the shared pair of electrons partially towards itself resulting in the hydrogen atom having a small positive charge on it and the oxygen atom having a small negative charge, thus causing polarity.

What is the difference between covalent polar covalent and hydrogen bonds?
Covalent - equal sharing of generally one pair of electrons (e.g. H2 hydrogen molecule)Polar covalent- ubequal sharing - the more electronegative element "attracts " the electrons in the bond towards it causing the formation of a small negative charge (and a small compensating positive charge on the less electronegative atom) example HCl, hydrogen chloride moleculeA hydrogen bond is a weak electrostatic bond invoving a hydrogen atom covakently bonded to one atom attracted to a very electrnegative atom. (Example is water, H2O)
