Use a sheet of paper to answer the following question. Take a picture of your answers and attach to this assignment. Predict the product formed in the nucleophilic aromatic substitution reaction between 1-chloro-2,4-dinitrobenzene and sodium methoxide (NaOCH3). Draw the mechanism of the reaction in (a), showing why the product you have selected is formed.

1-methoxy-2,4-dinitrobenzene

Explanation:

The nitro groups are strongly electron withdrawing and promote nucleophilic substitution reactions where one of the original substituents is removed and replaced by a strong nucleophile such as the methoxy group. The mechanism of the reaction is attached below. The electron withdrawing nitrogroup assists the formation of the intermediate in the reaction as shown.

the answer your looking for is c).

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
