Fatty acids are molecules with a carboxylic acid on one end and long hydrocarbon chain on the other. The sodium salts of fatty acids (such as sodium strearate, shown below) are commonly used in soaps to trap nonpolar dirt and grease particles. Soap does not work well in "hard water, which is water with high concentration of magensium and calcium ions (often found in water obtained from wells) Explain this observation at a molecular level.

Which of these is a hydroxyl group? A large organic molecule with different functional groups. A group marked A consists of a nitrogen atom and two hydrogen atoms attached to it. A group marked B consists of a phosphorus atom with four oxygen atoms. One of these oxygen atoms is connected to the phosphorus by a double bond. All other bonds are single. Two oxygen atoms have negative charges. A group marked C consists of a carbon atom connected to an oxygen atom by a double bond. A group marked D consists of an oxygen atom connected to a hydrogen atom. The group marked E consists of a sulfur atom connected with a hydrogen atom. A group marked F consists of a carbon atom, which is connected to one oxygen atom by a double bond and the other oxygen atom by a single bond. This last mentioned oxygen atom also has a hydrogen attached. EDACF
You are teaching a class in organic chemistry to grade 12 students. Outline the differences in 3 physical properties between alkanes, alcohols, and carboxylic acids. Note: they all have the same hydrocarbon length.
Draw Lewis structures and condensed structural formulas for the four alcohols with the molecular formula C4H10O. Classify each alcohol as primary, secondary, or tertiary. (Hint: First consider the connectivity of the four carbon atoms; they can be bonded either four in a chain or three in a chain with the fourth carbon as a branch on the middle carbon. Then consider the points at which the iOH group can be bonded to each carbon chain.)
How can you tell, from its chemical formula, if a hydrocarbon is an alkane, on one hand, or if there is a ring or pi bond on the other. Thank you.
Nucleotides are molecules that make up the structures of RNA and DNA. Modify the compounds to create adenosine monophosphate (AMP).

Consider the acid-base reaction between iodoethane (CH3CH2I) and hydroxide (-OH). CH3CH2I + OH- --> CH3CH2OH + l- Use the table of bond energies to estimate the change in enthalpy (∆H in kJ/mol) for this reaction. Think about the bonds that are broken and that are formed. This reaction is endothermic, exothermic or energy neutral Using your calculation, what can you say about the strengths of the bonds? -The bonds before the reaction are stronger than the bonds after the reaction. -The bonds after the reaction are stronger than the bonds before the reaction. or -The bonds before and after the reaction are equivalent in strength.
