Which combination of reagents used in the indicated order with benzene will give m-nitropropylbenzene? a. 1) CH3CH2CH2Cl/AlCl3,
VladimirAG [237]

Answer:

1) HNO3/H2SO4, 2) CH3CH2CH2Cl/AlCl3

Explanation:

Benzene is a stable aromatic compound hence it undergoes substitution rather than addition reaction.

When benzene undergoes substitution reaction, the substituent introduced into the ring determines the position of the incoming electrophile.

If I want to synthesize m-nitropropylbenzene, I will first carry out the nitration of benzene using HNO3/H2SO4 since the -nitro group is a meta director. This is now followed by Friedel Craft's alkykation using CH3CH2CH2Cl/AlCl3.

Why is it that when you have a strong acid and weak base your equivalence point is less than 7
yKpoI14uk [10]

Explanation:

When a strong acid, say HCl reacts which a weak base, say NH_3, the reaction is shown below as:-

\text{NH}_3 (\text{aq}) + \text{HCl} (\text{aq}) \rightarrow {\text{NH}_4^+}(\text{aq}) + \text{Cl}^-(\text{aq})

The salt further reacts with water as shown below:-

\text{NH}_4^+ + \text{H}_2\text{O} \rightarrow \text{H}_3\text{O}^+ + \text{NH}_3

Formation of \text{H}_3\text{O}^+ lowers the pH value of the solution as more hydrogen ions leads to less pH.

How many moles of ZnCl, will be produced from 23.0 g of Zn, assuming CuCl, is available in excess?
Dennis_Churaev [7]

Answer:

23 g of Zn will produce 0.352 mole of zinc chloride.      

Explanation:

Given data:

mass of Zn = 23 g

Moles of ZnCl = ?

Solution:

Chemical equation:

2Zn + CuCl₂ → 2ZnCl + Cu

Number of moles of Zn:

<em>Number of moles of Zn = mass/ molar mass</em>

Number of moles of Zn = 23 g / 65.38 g/mol

Number of moles of Zn = 0.352 mol

now we will compare the moles of ZnCl with Zn because it is limiting reactant.

                         Zn       :      ZnCl  

                         2         :        2

                         0.352 :        0.352

So 23 g of Zn will produce 0.352 mole of zinc chloride.
