The reaction of pyrrole with bromine forms predominantly __________. View Available Hint(s) The reaction of pyrrole with bromine
xenn [34]

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 Br_2 and FeBr_3. 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!

Caculate the number if moles of the following: 800. g of Ca
Maru [420]
Mole   is  equal  to   mass  of  the  element  divided  by   molar  mass  of  the  element.  that   is
mole=mass/molar  mass
From  periodic  table calcium  has  a   molar  mass  of  40   g/mol
moles  is   therefore  =800g/40g/mol=20moles

7. I have 2.50 x 1023 atoms of titanium. How many moles of titanium dol<br> have?
algol13

Answer:

0.42mole

Explanation:

Given parameters:

Number of atoms of titanium  = 2.5 x 10²³atoms

Unknown:

Number of moles  = ?

Solution:

To solve this problem, we must understand that a mole of any substance contains the Avogadro's number of particles.

              6.02 x 10²³ atoms makes up 1 mole of an atom

              2.5 x 10²³ atoms will contain \frac{2.5 x 10^{23} }{6.02 x 10^{23} }   = 0.42mole
