Select the reagents you would use to synthesize the compounds below from benzene. Use the minimum number of steps.
1 answer:
Answer:
A
C
Explanation:
For the reaction of m-bromonitrobenzene from benzene first, we need to carry out the nitration of benzene utilizing HNO3, H2SO4.
Bromination of nitrobenzene with Br2, FeBr3 outfits m-bromonitrobenzene in light of the fact that nitro group is meta coordinating for electrophile. The mechanism activity for the reaction is shown in the image below.

The answer to the question is
The change in the kinetic energy of the object is 600 J
Explanation:
The known variables are,
Mass of object, m = 100 kg
Force of object, F = 100 N
The relation for kinetic energy = KE = = 0.5·m·v²
Therefore to find v we first find the acceleration from
F = m·a =10.0 kg × a = 100 N,
Where a = acceleration of the object =100/10 = 10 m/s²
To find the velocity, v, we use the relationship
v² = u² + 2 × a × S, where S is the distance of motion = 6.00 m and u is the initial velocity, u = 0 m/s, therefore
v² = 0 + 2 × 10 m/s² × 6 m = 120 m²/s² or v = 10.95 m/s
Therefore KE = 0.5 × 10 kg × (10.95 m/s)² = 600 J
where the initial velocity, u = 0 m/s
Initial kinetic energy of the object = KE₁ = 0.5 × 10 × 0² = 0
The change in kinetic energy of the object = 600 J - 0 J = 600 J
