You analyze the products of a Ziegler-Natta reaction for the synthesis of polyethyleneusing FT-IR (a technique that uses infrared light to measure the identity and concentrationof functional groups in a sample). From FT-IR, you determine that you have 1 mmol ofmethyl groups. You also know that 1 mol of ethylene was consumed in thepolymerization. Assume that all chains are terminated with methyl groups. What is theapproximate degree of polymerization (DP)? Before answering this question, consider                 the ways in which the structure of polyethylene depends on polymerizationconditions! (How many methyl groups are there per chain?)(A) 1000(B) 2000(C) 500(D) 28,000 g/mol(E) 56,000 g/mol(F) 14,000 g/mol

Research in the “unzipping” of poly(vinyl chloride) indicates that certain defects in the polymer contribute to the rate of unzipping. These defects are arrangements of atoms that are different from the arrangements in the repeating unit shown in the condensed formula. Researchers have found that defects involving allylic chlorides and tertiary chlorides, specifically, promote the reaction. Review the mechanism for the unzipping and explain this observation.

Shown below is a carbocation intermediate in an electrophilic addition reaction of HCl with an alkene. For the conformation shown, select each hydrogen whose bond to carbon is aligned for effective hyperconjugation with the vacant p orbital on the positively charged carbon. Each adjacent carbon will have only one C-H bond so aligned. • Gray = C; white = H; red = 0; blue = N; dark green = Cl; brown =Br; light green =F; purple = I; yellow = S; orange = P. • Double click to select atoms. • You can zoom in and out using the mouse scroll wheel (or pinch to zoom on touch screens).

Draw the structure of the organic product of the reaction between cyclohexene and H2SO4, H2O.   Use the wedge/hash bond tools to indicate stereochemistry where it exists. Separate multiple products using the + sign In cases where there is more than one answer, just draw one.  Please make your answer clear. I did not understand the first answer because it was hand -written

The incomplete hydrogenation of alkynes (E) using H2 (g) and Lindlar's catalyst may not always go smoothly. Excessive "poisoning" of the catalyst could prevent any hydrogenation, leading to the retrieval of the initial material (D). Conversely, insufficient "poisoning" may result in complete hydrogenation, yielding the alkane (F).Describe the analytical method(s) you would employ (such as IR, NMR, UV/VIS, etc...) and detail the specific information you would seek to confirm the existence or nonexistence of D, E, and F.

In radical chlorination of alkanes, non-equivalent hydrogens react with chlorine atoms at different rates. At 35 °C, primary, secondary, and tertiary C-H bonds react at relative rates of 1: 3.9 : 5.2 respectively. These are conditions of kinetic control where product ratios are determined by relative rates of formation. For example, if A is formed twice as fast as B, the A:B product ratio will be 2. Consider chlorination of the alkane below at 35 °C. 1. Specify the most reactive C-H bond(s), a-c. Two non-equivalent C-H bonds of comparable reactivity should be separated by commas, i.e. a,c. 2. Specify the site of chlorination in the major monochloro substitution product, а-с. Two products that form in comparable quantities should be separated by commas, i.e. a,c
