<span>The atomic number is the number of protons in the nucleus. These are the only nuclear particles carrying charge; each carries a charge of 1 elementary unit.
</span><span>
answer = 11                                                                                                       just because that is the amount of protons it has and therefore positive charge</span>

The following questions are about ethyl bromide,n-propyl bromide, isopropyl bromide,t-butyl bromide, &amp; neopentyl bromide
mrs_skeptik [129]

Answer:

a) Watch the attaccment

b) Ethyl bromide is more reactive than n-propyl bromid, and this more than neopentyl bromide. Ethyl bromide has less steric hindrance than the others, to SN2 reactions.

c) t-butyl bromide is more reactive than  isopropyl bromide, and this more than ethyl bromide. t-butyl bromide structure stabilize the carbocation, better than the others.

Explanation:

Speed of SN2 reactions depends on steric hindrance, the less hindrance, the most reaction speed, meaning more reactivity. Then, those linear structures are more reactive to SN2 reactions.

In the other hand, speed of SN1 reactions depends on the stability of the carbocation formed. Structure with ramifications can stabilize better the carbocation, these structures are more reactive to SN1 reactions.

What is the equilibrium expression for the reaction below?
Mariana [72]

Answer:

A. K=\frac{[N_2O]^2}{[N_2]^2[O_2]}

Explanation:

Hello there!

In this case, for us to figure out the appropriate equilibrium expression, it will be firstly necessary for us to recall the law of conservation of mass which states that the equilibrium constant of an equilibrium chemical reaction is written by dividing the products and reactants and including the stoichiometric coefficients as exponents. In such a way, for the given reaction, we will have:

K=\frac{[N_2O]^2}{[N_2]^2[O_2]}

As N2O is the product whereas N2 and O2 are reactants; thus, the equilibrium expression will be A.

Regards!

Determine a detailed mechanism for the chlorination of benzene using cl2 and fecl3.
RUDIKE [14]
Step (1):
Generation of electrophile: by the action of Lewis acid FeCl₃ on Cl₂ to serve as a source of Cl⁺ (Electrophile)
Step (2):
Addition of electrophile to form carbocation:
addition of electrophile to form C-Cl bond and form carbocation which is stabilized by resonance.
Step (3):
Loss of proton to re-form the aromatic ring by the action of FeCl₄⁻ which removes proton from carbon containing Cl and forming the aromatic ring again
