Ammonia reacts with hypobromite OBr- as follows: NH3 OBr- ---> N2 Br- H20 which is the limiting reactant if 5.00 ml of 0.623
1 answer:
Answer:
Limiting reactant: NaOBr or OBr⁻.
Left over: 0.0006317 moles of ammonia remain unreacted.
Explanation:
Hello!
In this case, for the balanced chemical reaction:
Thus, when 5.00 ml of 0.623 M NaOBr react with 183 μL of 14.8 M NH3, in order to identify the limiting reactant, we first compute the moles of each reactant:
Now, we can compute the moles of any product, say nitrogen gas, produced by each reactant:
Therefore, since the hypobromite yields the fewest moles of nitrogen, we infer it is the limiting reactant. Moreover, for the left over of ammonia, we compute the required moles to yield 0.0010383 moles of nitrogen:
So the left over is:

Answer:but-1-ene
Explanation:This is an E2 elimination reaction .
Kindly refer the attachment for complete reaction and products.
Sodium tert-butoxide is a bulky base and hence cannot approach the substrate 2-chlorobutane from the more substituted end and hence major product formed here would not be following zaitsev rule of elimination reaction.
Sodium tert-butoxide would approach from the less hindered side that is through the primary centre and hence would lead to the formation of 1-butene .The major product formed in this reaction would be 1-butene .
As the mechanism of the reaction is E-2 so it will be a concerted mechanism and as sodium tert-butoxide will start abstracting the primary hydrogen through the less hindered side simultaneously chlorine will start leaving. As the steric repulsion in this case is less hence the transition state is relatively stabilised and leads to the formation of a kinetic product 1-butene.
Kinetic product are formed when reactions are dependent upon rate and not on thermodynamical stability.
2-butene is more thermodynamically6 stable as compared to 1-butene
The major product formed does not follow the zaitsev rule of forming a more substituted alkene as sodium tert-butoxide cannot approach to abstract the secondary proton due to steric hindrance.
