2,4-Dimethylpent-2-ene undergoes an electrophilic addition reaction in the presence of HBr to form 2-bromo-2,4-dimethylpentane.

Complete the mechanism of this addition and draw the intermediates formed as the reaction proceeds.
Draw all missing reactants and/or products in the appropriate boxes by placing atoms on the canvas and connecting them with bonds. Add charges where needed. Electron flow arrows should start on the electron(s) of an atom or a bond and should end on an atom, bond, or location where a new bond should be created.

Answer:

the answer is in the diagram

Explanation:

when 2,4-dimethylpent-2-ene undergo electrophilic addition reaction in the presence of HBr to form 2-bromo-2,4-dimethylpentane, it firstly lead to an intermediate carbocation

A carbocation can be describe as an organic molecule, which serves as an intermediate, that has a carbon atom bearing a positive charge and three bonds instead of four

Why doesn't the density of the object change when you adjust the mass and volume of the objects?
Pachacha [2.7K]
Because as you change the mass the volume will change and as you change the volume the mass will change too, it's a constant ratio for each element. Mass and volume are not factors that affect the density. factors that affect the density are temperature and type of the material/element

The exponents in the rate law of an elementary step are always equal to the coefficients of each species in the balanced reactio
Naya [18.7K]

Answer:

True

Explanation:

True. Since in an elementary step , the reaction procedes by collision of the atoms of reactants involved and since the rate of collision is proportional to the concentration of each atom that participates in the elementary step , the exponents in the rate law of the elementary step always coincides with the coefficients that correspond to that reaction ( regardless if is unimolecular, bimolecular or trimolecular).

A chamber has a pressure of 1.5 atm at a volume of 1.4 L. What is the pressure when the piston compresses the sample
nordsb [41]

Answer:

C.) 3.5 atm

Explanation:

Because you are dealing with pressure and volume, you can use Boyle's Law to help you find the missing variable. The general formula looks like this:

P₁V₁ = P₂V₂

In this formula, "P₁" and "V₁" represent the pressure and volume of the chamber originally. "P₂" and "V₂" represent the final pressure and volume. You have been given the values of all the other variables but "P₂". Therefore, you can plug these values into the formula and simplify to find the final pressure.

P₁ = 1.5 atm

V₁ = 1.4 L

P₂ = ?

V₂ = 0.60 L

P₁V₁ = P₂V₂                                        <---- Boyle's Law formula

(1.5 atm)(1.4 L) = P₂(0.60 L)               <---- Plug in values

2.1 = P₂(0.60 L)                                 <---- Multiply 1.5 and 1.4

3.5 = P₂                                             <----- Divide both sides by 0.60

Enter a balanced equation for the reaction between aqueous lead(II)(II) nitrate and aqueous sodium chloride to form solid lead(I
aev [14]

Answer:

Pb(NO₃)₂ (aq)  + 2NaCl (aq)  → PbCl₂ (s) ↓  + 2NaNO₃ (aq)

Explanation:

The reactants are:

Lead(II) nitrate → Pb(NO₃)₂ (aq)

Sodium chloride → NaCl (aq)

The products are:

Lead(II) chloride → PbCl₂ (s)

Sodium nitrate → NaNO₃ (aq)

Salts form nitrate are soluble. The chloride makes a precipitate with the Pb²⁺. The chemical equation for this reaction is:

Pb(NO₃)₂ (aq)  + 2NaCl (aq)  → PbCl₂ (s) ↓  + 2NaNO₃ (aq)
