Interpretation The H1 spectra for various resonance to the hydrogen nuclei responsible for them intrans-4-methyl-2-pentene needs to be determined.
Concept Introduction:
Spectroscopy is the method of identification of structure of the organic molecules with the help of their absorption of certain electromagnetic radiations.
The H1spectroscopy or NMR is based on the nuclear magnetic resonance of radio waves on the H atoms bonded to C atoms present in the organic molecule.

Why was it important to have dry equipment that was heated in oven and a drying tube placed on top of the condenser for the above-mentioned reaction? Explain?arrow_forward7. Why is water a suitable solvent for this recrystallisation? 8. Calculate the concentration in mol dm-3 of 10 w/v% sodium hydroxide. 9. Write down an organic chemistry mechanism (use curly arrows) for the transformation of benzamide to benzoic acid, via its sodium salt.arrow_forwardWrite a mechanism that accounts for the formation of ethyl isopropyl ether as one of the products in the following reaction. A. Write the mechanism for step one of this reaction. Show lone pairs and formal charges. Only the acidic hydrogen should be drawn out with a covalent bond. B. Write the mechanism for step two of this reaction (where the product of step one reacts with the solvent, ethanol). Show lone pairs and formal charges. Only the acidic hydrogen should be drawn out with a covalent bond. C.Write the mechanism for the last step of this reaction (formation of ethyl isopropyl ether). Show lone pairs and formal charges. Only the acidic hydrogen should be drawn out with a covalent bond. Cl- will act as the base in this reaction.arrow_forward
- TLC, a powerful analytical tool, can be used to monitor the progress of reactions. The synthesis of ethyl-3-coumarincarboxylate can be monitored by TLC by displaying the starting aldehyde 1, and coumarin product 2, which have very distinct Rf values (Hint: Think about the polarity of compounds 1 and 2 in terms of their abilities to H-bonds to silica gel). What can be determine about the progress of the reaction from analysis of the TLC shown below?arrow_forwardIn an electrophilic aromatic substitution: Friedel-Crafts alkylation, where the tert.-butyl cation is used to alkylate 1,4-dimethoxybenzene.arrow_forwardCan you list the possible sources of error that can affect the yield of a Grignard reaction followed by extractions?arrow_forward
- Propose a structure for an aromatic hydrocarbon, C3H10, that can form three C3H,Br products on substitution of a hydrogen on the aromatic ring with bromine. • You do not have to consider stereochemistry. In cases where there is more than one answer, just give one. • Ignore the ortho, para-directing effects of the alkyl groups in answering this question. Consider only the number of nonequivalent hydrogens on the aromatic ring. .... ChemDoodlearrow_forward1. In the reactions involving the three isomeric alcohols with the formula C4H9OH, describewhat each of the following tests showed about reactivity of the -OH group and reactions of 1°,2°, and 3° alcohols.• the test with neutral KMnO4• the test with concentrated HCl2. Predict how the fourth alcohol with the formula C4H10O would react if tested with:• 0.01 M KMnO4• concentrated HCl at room temperatureExtend FurtherUse your observations of the solutions formed in the previous experiments and yourunderstanding of alcohols to complete a table like the one shown below.
