- why is this S not R（I means the one that I circle in red color） 123 or 134？？？if go 123 it would be R，if it goes 134，it would be s？so confusing？Can anyone make it clear？Please help and explain in detailsWhich amomg the fragments below will be dectected by mass Spectrophotometer? [CH3CH3]+ CH3CH3 •CH2CH3 [CH3CH4]- only ii i and iii only i ii and iv only iiPlease explain how to solve the following NMR:
- How do you assign R or S to a molecule when the lowest-priority group is not oriented toward the back, on a dashed wedge?Can you explain spectroscopy? Let's start with NMR Spectroscopy. What is the difference between a proton being enantiotopic and homotopic? What does it mean for a proton to be shielded or deshielded? How do you determine J (the coupling constant)? What does 'coupling is mutual' mean? How is that translated on the NMS Spectroscopy spectrum? Does that have to do with the polarity of the molecule? Is there an easier way to explain that? When thinking about C-13 NRM Spectroscopy, what it meant by the statement, "the carbons cannot integrate"? When looking at an NMR Spectroscopy spectrum, how do you know which peak belongs to which proton? (The intensity of the peak and the ppm of the peak) P.S. These questions come from after watching a lecture. There is no graded assignment attached to these questions. I simply do not understand the material.C13 HNMR Spectroscopy, please solve this problem and explain it..
- Determine which protons refers to each peak shown on the graph below. (there are 7 of them) ( plz do completely in detain plzz .given handwritten solution in A4 size paper , plz give ans in detail )Why is it that D hydrogens have a higher chemical shift than the E hydrogens? Aren't the D hydrogens less shielded than the E hydrogens which have carbons surrounding on both sides? And less shielding means higher chemical shift required?NMR HW help . which one is correct structure that match the NMR graph and explain why
- 1 Can one distinguish between the Markovnikov and anti-Markovnikov complement products I and II byinfrared spectroscopy? How about nuclear magnetic resonance? Justify your answersI need help finding the functional groups and the wavelegth for the coumpound and to draw the is spec based on the wavelegth and label them on the compund and ir spec I linked and example of one that i already did and it needs to look like itGive a to d answer plz ?
