Hydrogen

different products: 1-heptene, Cis-2-heptene and Trans-2-heptene. However, the major product constituent was 1-heptene. Because Potassium TertButoxide is a bulky base, steric hindrance prevents it from attacking a hydrogen on a highly substituted carbon. Consequently, the base attacks a hydrogen on the least substituted carbon (primary carbon). In this case, steric hindrance is reduced and the elimination reaction is faster, so a less substituted alkene is more favored, and becomes the major…

by bonding hydrogen and oxygen molecules. This process allowed Mark Wattney to create 600 liters of water that he would have otherwise died without. A hydrogen bond is the electromagnetic attraction exerted between polar molecules where hydrogen is bound to a larger atom. An example of this would be a hydrogen atom bonding to an oxygen or nitrogen atom. A water molecule is formed by 2 negatively charged hydrogen atoms attaching to a positively charged oxygen atom. This is why hydrogen bonding…

STEPS IN BALANCING REDOX EQUATIONS 1) Assign the Oxidation Numbers The Oxidation Number (ON) of an element is its charge. It is the number of electrons an element contains. This would be our basis on whether the element gained or lost electrons in chemical reactions. We can say that an element is in its Oxidation State when the element already has a specific ON. Unlike with our previous examples, not all equations would already reveal the ON of each element. In actuality, equations would…

Reduction involves increasing the number of carbon hydrogen bonds by adding hydrogen across a double or triple bond which results in an increase in electron density at the carbon atom. Organic functional groups containing double and triple bonds which undergo reduction are unsaturated. The reduction of the double bond by addition of hydrogen atoms results in the product being fully saturated. Metal hydride reducing agents that have different reactivities toward specific functional groups are…

In experiment 2, we observed that the reaction of halogenoalkanes with aqueous alkali and water which contains dissolved silver nitrate. Halogenoalkanes are alkanes which have one or more hydrogen atoms replaced by halogen atoms such as fluorine (F), chlorine (Cl), bromine (Br) and iodine (I) which are the elements in group 7 in periodic table. Halogenoalkanes have the general formula, RX, whereby R is an alkyl or substituted alkyl group and X is any of the halogen atom. Besides, halogenoalkanes…

Buoy 21, Day Mark 1, Pelican Island Cut, and the Coast Guard Station. The main ingredient in saltwater is water. Water is composed of two hydrogen atoms and one oxygen atom that are covalently bonded and forms a polar molecule because the electrons are shared unequally. The unequal distribution causes the oxygen atom to have a negative pole and the two hydrogen atoms have a positive pole. The polarity of water makes it unique and allows it to perform as a solvent (Duke University, n.d.). Since…

interaction of hydrogen, carbon and the radical itself, and termination which is the recombination of stable molecules. Toluene: Ethylbenzene: Isopropylbenzene: t-butylbenzene The purpose of this lab was to observe the speed at which the process of halogenation took place in molecules with carbons of varying stature…

catalyzed by catalase is the decomposition of hydrogen peroxide to form water and oxygen, which occurs spontaneously, but not at a very rapid rate. Write a balanced equation for this reaction. Label the reactant and the product. (Remember that catalase is not a reactant or a product and can be written over the arrow separating the reactant from the products.) I will help you with the equation. Catalase 2H2O2 ------------------------> 2H2O + O2 (g) (Hydrogen peroxide) (Water) (Oxygen) 2.…

symmetry as well, because of the formation of hydrogen bonds between the hydrogen molecules. Phase III now has the highest degree of symmetry, formed from the said hydrogen bonds and their geometrical arrangement. When the temperature is raised 400K, Phase II starts to occur. The hydrogen bonds mentioned above in their geometrical arrangement are now changed to form in a [310] direction, and the molecule now exhibits vertical…

in our cells is double stranded � there are two strings of nucleotides that are joined primarily by hydrogen bonds between the strands. We mentioned earlier that hydrogen bonds, when considered as individual bonds, are very weak. However, when we consider hundreds of hydrogen bonds together, a relatively strong and stable structure can result. Nucleotides from one strand make two or three hydrogen bonds with complimentary nucleotides of the other strand, depending on the nucleotide pair. The two…
