**Question:** A nucleus that is shielded will appear ______ in the NMR spectrum.**Options:** A) downfield B) upfield---In the context of NMR (Nuclear Magnetic Resonance) spectroscopy, a shielded nucleus will appear upfield in the spectrum. The concept of shielding refers to the electron density around a nucleus, which affects the magnetic environment experienced by the nucleus. Higher electron density around a nucleus provides more shielding, causing the NMR signal to appear at a higher chemical shift value, or "upfield."**Explanation of Terms:**- **Upfield:** Refers to the higher frequency (lower energy) side of the NMR spectrum, typically represented by a lower chemical shift value.- **Downfield:** Refers to the lower frequency (higher energy) side of the NMR spectrum, usually represented by a higher chemical shift value.In summary, in NMR spectroscopy, shielded nuclei resonate at lower chemical shift values, appearing upfield in the spectrum.

on 19 of 42 > Learning Loudon Parise SEVENTH EDITION Construct a simulated ¹H NMR spectrum, including proton integrations, for CH₂ OC(CH₂OCH (see Hint). Drag the appropriate splitting patterns to the approximate chemical shift positions; place the integration values in the small bins above the associated chemical shift. Splitting patterns and integrations may be used more than once, or not at all, as needed. Likewise, some bins might remain blank. Note that peak heights are arbitrary and do not indicate proton integrations. 30円 $ 4 R F V 7 % 5 T G B ^ 6 2H -Fo Y H MacBook Air & 7 RAM N 4 U Answer Bank J * 00 M 9H I ( 9 K ➤➤ 2 O < H ) O L 6H command P -3H sented by Macmillan Learning ^ 11 ; 0 ppm 95 { + 11 alt ? option } (1)

A.) How many signals does the HNMR of the unknown C6H14O have? B.)Whats the ratio between the number of different hydrogens in the unknown compound C6H14O? C.)Explain splitting patterns of all the signals (in depth if possible the lecture confused me). D.)Explain the chemical shifts of the signals based upon the locations of hydrogens relative to the desheilding groups if any are present in the compound. For A. I think there are 4 signals. For B. I think the ratio is 1:1:3:9 for the hydrogens on the HNMR spectrum. For the last 2 questions (C. and D.) the lecture confused me so an in depth of how you found the answer would be greatly appreciated. Also the unknown for the attached HNMR is C6H14O.
