Notes Aldehydes and Ketones The major similarity between an aldehyde and a ketone is the carbonyl group. A carbonyl group is a carbon atom doubly bonded to an oxygen atom. [pic] Both molecules have a carbonyl group‚ the difference the number of carbons bonded to the carbonyl carbon. An aldehyde will have none or one and a ketone will have two carbons. All aldehydes‚ except formaldehyde‚ will have a hydrogen atom on one side of the carbonyl carbon and at least on carbon on the other side

moles) of solute per liter of saturated solution. The solubility of one compound in another is related to the strength and type of intermolecular forces that exist between the two components. These forces arise from factors of molecular shape and electronegativity difference (∆χ)‚ and are influenced by the specific functional groups contained within the molecule. A functional group is a group of atoms bonded in a particular way‚ with a predictable chemical and physical behavior. Examples are shown in Figure

to use the periodic table to identify metals‚ semimetals‚ non metals‚ and halogens. c. Students know how to use the periodic table to identify alkali metals‚ alkaline earth metals and transition metals‚ trends in ionization energy‚ electronegativity‚ and the relative sizes of ions and atoms d. Students know how to use the periodic table to determine the number of electrons available for bonding. I explain to my students that columns 4A-7A are ’wanna be’ noble gases‚ ie want 8 valence

The water came from outer space to Earth. The water was brought to the planet for the comets. The water has a different structure for each state (gas‚ liquid‚ ice). Liquid water has random molecules. On the other hand‚ the ice has a more stable structure. The different structure between ice and liquid water can explain why the ice has less density than liquid water. Temperature is responsible for increasing the dissolution of components‚ and electrical conductivity. Pure water is not a good conductor

stomach acids‚ it can also be found in water purification‚ disinfectants‚ bleach‚ medicine‚ and mustard gas. Furthermore‚ when looking at the periodic table trends‚ pH is more basic as you go from left to right‚ which is also the same for the electronegativity trend. This means that your alkali metals are more acidic than the noble

is a brown liquid‚ I2 is a blue-black solid. • In Group 7‚ boiling point increases down the group because the molecules have more electrons and‚ therefore‚ stronger van der Waal’s forces which require more energy to overcome them • Electronegativity is the ability of an atom to attract the electrons in a covalent bond • Down Group 7‚ the shared electrons are further from the nucleus and more shielded. There is a weaker attraction for the bonding electrons down the Group 2) Trends

Summer Assignment – AP Biology – Chapters 2-5 Chapter 2 1. CHNOPS are the six most crucial elements in most macromolecules. Name them. Carbon‚ Hydrogen‚ Nitrogen‚ Oxygen‚ Phosphorous‚ Sulfur. 2. Create a chart and state how many bonds each of the CHNOPS elements can form. Carbon | Hydrogen | Nitrogen | Oxygen | Phosphorous | Sulfur | 4 | 1 | 3 | 2 | 3 or 5 | 2 | 3. Create a Venn Diagram to compare and contrast polar covalent bonds‚ nonpolar covalent bonds‚ and ionic bonds.
