It is A I took it befor hope this helps:)
Answer:
Here's what I get
Explanation:
(a) Intermediates
The three structures below represent one contributor to the resonance-stabilized intermediate, in which the lone pair electrons on the heteroatom are participating (the + charge on the heteroatoms do not show up very well).
(b) Relative Stabilities
The relative stabilities decrease in the order shown.
N is more basic than O, so NH₂ is the best electron donating group (EDG) and will best stabilize the positive charge in the ring. However, the lone pair electrons on the N in acetanilide are also involved in resonance with the carbonyl group, so they are not as available for stabilization of the ring.
(c) Relative reactivities
The relative reactivities would be
C₆H₅-NH₂ > C₆H₅-OCH₃ > C₆H₅-NHCOCH₃
The major species in solution when solid ammonium bromate is dissolved in water is shown below
Answer:
156.8kPa
Explanation:
The problem here is to convert mmHg to kPa;
We have been given:
1176mmHg and the problem is to convert to kPa;
1000Pa = 1kPa
1 mmHg = 133.322Pa
1176mmHg will give 1176 x 133.322 = 156787.1Pa
To kPa;
156.8kPa
