The reason for the trend in the previous question is because Bromine is electron density from the carbon the proton is on, resulting in the proton being , thus the proton nuclei is effected by the applied magnetic field leading to a greater difference in energy of the nuclei's spin states.

Explanation:

From this question, we are to fill in the blanks with the appropriate correct answers.

NOTE: that the electron-withdrawing groups decrease the electron density around the proton nucleus and therefore the nucleus feels the external magnetic field more. Hence, it requires a larger frequency to attain resonance(downfield).

explanation:

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
