Answer:
repeat the experiment
Explanation:
I am big brain. if she wants to know if it is correct, repeating the exact ay would show her if it is right or if she did something wrong
Increase, because you need heat to melt a solid to a liquid, so the temperature will have to get greater.
Covalent bond two non metals
the element hydrogen atom is made up of oxygen atoms.
Answer:
a) 2-bromopyrrole
Explanation:
Our options for this questions are:
a) 2-bromopyrrole
b) 2,3-dibromopyrrole
c) N-bromopyrrole
d) 3-bromopyrrole
To understand how the reaction works we have to start with the <u>resonance structures</u>. (Figure 1), on these structures, we will obtain a n<u>egative charge on carbon 2</u> in the pyrrole ring, therefore on this carbon we can generate an attack to an electrophile.
The second step is to check how the mechanism take place. An <u>electrophile is generated</u> by the
and
. This electrophile can be <u>attacked</u> by the negative charge on carbon 2 producing the 2-bromopyrrole. (See figure 2).
I hope it helps!
