The acetyl group some of the electron density the nitrogen, making it much basic; the nitrogen of this amide is under the reaction conditions. The N retains enough electron density to share with the benzene ring, so the NHCOCH3 group is still an activating -director, though weaker than NH2.

The gaps are filled using the following;

1. removes

2. from

3. less

4. Protonated

5. Ortho, para

Explanation:

Electron density is removed from nitrogen in acetyl group which is why it is less basic

The complete sentences is now written as;

The acetyl group removes some of the electron density from the nitrogen, making it much less basic; the nitrogen of this amide is protonated under the reaction conditions. The N retains enough electron density to share with the benzene ring, so the NHCOCH3 group is still an activating ortho, para director, though weaker than NH2.

answer: mole of the gas

answer: mole of the gasexplanation:

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
