Answer:
See figure 1 and 2
Explanation:
In this case, we can start with the general reaction. Acetanilide with bromine in acetic acid we will produce <u>p-bromo-acetanilide</u> (See figure 1).
In the reaction mechanism, we have as first step the attack of the double bond in the benzene ring to one of the Br atoms in bromine (
) and a positive carbon will be produced in benzene. This positive charge can be moved inside of the benzne ring producing the r<u>esonance structures A, B and D</u>. Resonance structure C is produced when a double bond is generating between the "N" atom and the carbon in the benzene ring.
The final step in the mechanism is when we remove the "H" atom in structure A to produce again the double bond.
See figure 2
I hope it helps!
Answer:
b. The number of electrons
Explanation:
A "neutral atom" has a <u>neutral charge</u>. This means that <em>its charge is equal to </em><em>zero. </em>In order for the charges to cancel out each other, the atom's <em>positive charge should be equal to the negative charge. </em>These being said, the number of electrons<em> (negatively-charged)</em> is then equal to the number of protons <em>(positively-charged). </em>Those atoms which are not neutral are called <em>"ions."</em> This means that they either have more or less electrons than the protons.
Answer:
The third option should be right
Answer:
The answer is below
Explanation:
1. With the aid of natural hues, the fox can change its color based on the environment it found itself in. For example, during summer and spring, fox color changes to dark to provide itself cover in the environment that is characterized by the brown dirt. Similarly, the fox color changes to white during winter and fall to blend with the snow.
2. In a bid to domesticate fox, it has been observed over many generations that the domesticated fox compared to wild fox has floppy ears and curly tails. The stress hormone level has reduced significantly and they possess a smaller adrenal gland.
Answer:
[He]2p6
Explanation:
Fluorine has an atomoc number of 9 which means 9 electrons with the electon configuration:[He]2p5,However,when it becomes Fluoride ion,it gains one electron to complete its outermost shell to obtain an octet configuration and becomes [He]2p6.
