    are Polymers and Why Use Carbon and Silicon Atoms? Polymers are repeating chains of monomers (atoms) which link in varying trends depending on their individual properties. These properties determine such aspects of the polymer such as solubility‚ reactivity‚ state (liquid‚ solid‚ gas)‚ conductivity‚ melting point‚ boiling point and freezing point. Also‚ the atoms surrounding the polymer chains determine the charge (negative or positive). (For example‚ a Hydrogel chain (without the addition of Sodium

    conditions‚ a bromohexane compound is synthesized from 1-hexene and HBr(aq). The desired product‚ 2-bromohexane‚ is analyzed to see if it is produced according to Markovnikov’s rule‚ which states that when an alkene reacts with a hydrogen halide (HBr) to form an alkyl halide‚ the H+ is added to the carbon with a greater number of hydrogen substituents to form a more stable carbocation and the halogen (Br-) is added to the carbon with fewer hydrogen substituents. A heterogeneous mixture of 0.5mL of 1-hexane

    Note that not only is this reagent a primary halide‚ but it also has no _-hydrogens (so no E2 is possible). Finally‚ our reaction solvent is DMF (N‚N-dimethylformamide)‚ a classic solvent for SN2 reactions. With all the conditions in favor of this reaction‚ it should be no surprise that this reaction works very well Despite the ease of our reaction‚ a few comments are in order. Our alkyl halide‚ cinnamyl bromide‚ is extremely reactive. As an electrophile‚ it is activated

    Chapter:-8 The d-and f-Block Elements POINTS TO BE REMEMBERED: --- The elements of periodic table belonging to group 3 to 12 are known as d-Block elements. The general electronic configuration of these elements is (n -1)d1-10 ns 1-2 d- Block elements are collectively known as Transition Elements because properties of these elements vary in between s-Block and p-Block elements. A transition element should have partially filled (n-1) d orbital. Group 12 elements i.e. Zn

    described previously‚ primary alkyl halides generally undergo substitution reactions with simple nucleophiles by an SN2 mechanism. Secondary alkyl halides‚ often react with simple basic nucleophiles to give a mixture of products arising from both substitution and elimination. As with substitution reactions‚ the rate at which elimination reactions proceed can be proportional to both the concentration of the base and the concentration of the reactant alkyl halide (an "E2" reaction (elimination bimolecular)

    aeration time‚ the formation of the iron oxy-hydroxide species and also coating the surface with these species increase. Then‚ however‚ because of the coverage of most of the pyrite surface by these species‚ a significant decrease in the surface reactivity with oxygen occurs. In other words‚ with further increase in aeration time‚ the pyrite surface is
