Answer:
3 > 2> 1
Explanation:
Aromatic compounds undergo electrophilic substitution reaction which passes through a positively charged intermediate to yield the product.
Substituted benzenes may be more or less reactive towards electrophilic aromatic substitution than benzene molecule depending on the nature of the substituent.
Certain substituents increase the ease of reaction of benzene towards aromatic substitution.
If we look at the compounds closely, we will notice that toluene reacts readily with CH3Cl / AlCl3. This is because, the methyl group is electron donating hence it stabilizes the positively charged intermediate produced in the reaction.
Carbonyl compounds are electron withdrawing substituents hence they decrease the magnitude of the positive charge and hence decrease the rate of electrophilic aromatic substitution.
Answer False
Explanation: Friction makes it stop at some point. For it to have an unlimited speed goes against beset is first law that states an object in motion with stay in motion unless acted upon by an external force, your force will be the friction of the wheels on the roller coaster
4km I believe is the answer
Answer:
Atoms are indivisible
I had a hard time finding this out.
Explanation: Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. Dalton based his theory on the law of conservation of mass and the law of constant composition. The first part of his theory states that all matter is made of atoms, which are indivisible.
Explanation:
<h3>Here, mass = 5kg </h3><h3> acceleration = 10m/s^2</h3>
<h3>according to the question ;</h3><h3>F = m×a ( from 2nd law of motion)</h3><h3>F = 5kg × 10m/s^2</h3><h3>F = 50kgm/s^2 or NEWTON </h3>
<h3>SO THE FORCE NEEDED IS 50 NEWTON</h3>
