Water molecules are polar• For reasons we won't getting into here, an oxygen atom has two bonding sites that are fairly close toone another. Thus when two H atoms bond to O to form a water molecule, the entire watermolecule is BENT like the letter “V".• Where are most of the electrons: near the oxygen or near the hydrogens?The whole water molecule is polar with a partially positive pole and a partiallynegative pole, like a little magnet. On the ball-and-stick model to the right, labelthe partially positive atoms, and the partially negative one.

On the basis of charge distribution between the participating atoms, the molecules can be polar and…

Figure 2.24 Which of the following statements is false? Molecules with the formulas CH3CH2COOH and C3H6O2 could be structural isomers. Molecules must have a double bond to be cis-trans isomers. To be enantiomers, a molecule must have at least three different atoms or groups connected to a central carbon. To be enantiomers, a molecule must have at least four different atoms or groups connected to a central carbon.
Each carbon molecule can bond with as many as other atom(s) or molecule(s). one two six four
Watch this video (http://openstaxcollege.org/l/disaccharide) to observe the formation of a disaccharide. What happens when water encounters a glycosidic bond?
Which of the following is not a property of water? a. It has a low boiling point compared with other molecules. b. It has a high heat of vaporization. c. Its molecules resist separation, a property called cohesion. d. It has the property of adhesion, the ability to stick to chargedand polar groups in molecules. e. It can form hydrogen bonds to molecules below but not aboveits surface.
The water lattice: a. is formed from hydrophobic bonds. b. causes ice to be denser than water. c. causes water to have a relatively low specific heat. d. excludes nonpolar substances. e. is held together by hydrogen bonds that are permanent; that is, they never break and reform.
The chemical activity of an atom: a. depends on the electrons in the outermost energy level. b. is increased when the outermost energy level is filled withelectrons. c. depends on its 1s but not its 2s or 2p orbitals. d. is increased when valence electrons completely fill the outerorbitals. e. of oxygen prevents it from sharing its electrons with otheratoms.
What about Hydrogen? Since Hydrogen (H) has one proton, it only has one electron. That means that Hydrogen can share or be stolen from depending on which element it’s reacting with. So, Hydrogen can do both! Are you ready to look more closely at Hydrogen? Group of answer choices True False
Draw a “dot & cross” diagram to show the shape of a water molecule (H2O). Bond angles need to be shown. State the shape of a water molecule.
___________ covalent bonds are between atoms which share the e- equally. Atoms will vary in their ________________________ and are often driven to pull on electrons from covalent bonds.
Hi there- could you please let me know what "reactions occur" in each part of the structure?
1. Draw a circle around and give the name of each functional group in the following twomolecules. (Note: each line represents a covalent bond. If no atom is shown, assume there’s a carbon there.)
Please ASAP. Thanku. Explain in detail why water molecules are polar. Your explanation can be as long as you wish. Your answer must be in your own words. Your answer must include the following terms: Polar, polar covalent bonds, electronegativity, oxygen, hydrogen, partial positive, partial negartive, electrons.
