It is known that chlorine is more electronegative than bromine, and thus chlorine is more reactive, and less discriminatory as to what it will react with, thus making bromine more “selective”. Another pertinent piece of information to look at would be stability. The stability of a free radical increases as the number of carbon substituents increases. Therefore, primary is the least stable and tertiary is the most stable. Also, the more stable the free radical that is left behind, the weaker its C-H bond strength will be.
With the use of this technique we placed chlorine, bromine, and iodine into solutions containing chloride, bromide, and iodide. In the reaction the free halogen (X2) oxidizes the other halide ion (Y-) and gets reduced by gaining electron(s). In table 3, chlorine was the strongest oxidizing agent and iodine was the weakest oxidizing agent. Since chlorine was the strongest oxidizing agent it will react more and the weak agent will react less. This explanation can be demonstrated in table 3 also because the results of the reactions demonstrates that chloride reacted more by the color of the product compared to the color of chloride in the mineral oil.
(Nitrogen, hydrogen, oxygen, carbon dioxide, and other elements cause weld defects if introduced to the weld pool.) After a while it was discovered that argon has some advantages over helium. Because argon is heavier than helium, less flow rate is needed. The lower flow rate requirement makes argon better for flat welding. Helium is good for overhead, because it is lighter and thus flows upward.
Which type of intermolecular attraction (dispersion force, or hydrogen bond) exists in each of the following liquids? hydrogen bond hydrogen bond dispersion force hydrogen bond Predict which liquid in each pair has the higher boiling point. CH3COOH C2H5OH If the molecules in a liquid are weakly attracted, which of the following properties has a high value? vapor pressure (high when attraction is low) boiling point is low (it is only high when molecules are strongly attracted) viscosity is low (it is only high when molecules are strongly attracted) surface tension is low (it is only high when molecules are strongly attracted) Distinguish between a solid and a liquid at the molecular level. Solids and liquids differ at
It is not combustible, but it speeds up the combustion of other substances because it is an oxidizing agent. It can react with combustible materials and emit toxic fumes. It is used in paint and ink pigments, as a wood preservative, or a corrosive inhibitor. It is a carcinogen to humans. Product A- Silver Chromate(s)~Ag2CrO4 Silver Chromate is a reddish-brown crystalline substance.
Hydrogens on the alkene have different reactivity which determines which isomer is favored. Hydrogens attached to carbons, and have a weak bond strength are most reactive therefore are favored during abstraction by chlorine. The chloro substituent has an effect on carbon reactivity due to the chlorine atom being an electron withdrawing substituent. The chlorine
The metallic elements in this experiment support that they form acidic oxides. Cesium would be much more reactive than both calcium and potassium. Francium would be the most reactive metal in Group 1. It would be acidic. They were basic.
B) permanent dipoles of molecules containing covalent bonds between atoms of very different electronegativities. C) the hydrophobic effect. D) ion pairing between oppositely charged functional groups. Answer: A Page Ref: Section 5 28) The aggregation of nonpolar molecules or groups in water is thermodynamically due to the A) increased entropy of the nonpolar molecules when they associate. B) decreased enthalpy of the system.
pH > 7 is alkalinity environment that will bind hydrogen ion, and pH < 7 is acidic environment that will donate hydrogen ion. On the other hand, increasing hydrogen ion concentration will reduce the bound metal cation concentration. Decreasing hydrogen ion concentration will increase the hydroxyl ion concentration (M. Chaplin, 2004). Enzymes are one of the most efficient catalysts in biochemical reactions. They are used to speed up the reaction rates by providing an alternative reaction pathway of lower activation energy, which is the minimum energy that requires for reactions occur.
Alkanes respond with halogen, (for example, chlorine or bromine) when the mixture is presented to ultraviolet light (symbolized as hv or UV) or when warmed to high temperature (200 - 400c)). The capacity of ultraviolet light is to give vitality to the homolytic cleavage of halogen (Cl-Cl or Br-Br). The items are haloalkanes (RX) and hydrogen halides (Hx) .The halogenation of alkanes is a free radical substitution response, in which the system includes start, spread and end steps. The monosubstitution of alkanes alludes to the substitution response where there is one and only hydrogen molecule in alkanes substituted by halogen free radical. General mechanism The chain component is as per the following, utilizing the chlorination of methane as an issue illustration: 1.
