Draw the major 1,2- and 1,4-addition products that form as a result of the following reaction between one equivalent each of 2,4
lapo4ka [179]

The major 1,2- and 1,4-addition products are 4-Bromo-2-hexene and 2-Bromo-2-hexene.

What is Markovnikov Rule ?

Markovnikov rule explains that in addition reaction of alkene react with a hydrogen halide. The hydrogen atom is attached to the carbon atom that is already bonded to the greatest number of hydrogen.

<h3>What is Addition Reaction ?</h3>

An addition reaction is an organic reaction occur when two or more molecules combine to form a larger molecule without the loss of any atoms present in reactant.

Thus from the above conclusion we can say that The major 1,2- and 1,4-addition products are 4-Bromo-2-hexene and 2-Bromo-2-hexene.

If the pressure of a gas is quadrupled (4x), how
umka2103 [35]

Answer:

Yes. The volume would be 1/4 of the initial volume.

Explanation:

At constant temperature, the pressure of a gas is inversely proportional to the volume of the gas. Hence;

P1V1 = P2V2

<em>where P1 is the initial pressure, V1 is the initial volume, P2 is the final pressure, and V2 is the final volume.</em>

If the pressure of a gas is quadrupled;

P2 = 4P1, the equation becomes

P1V1 = 4P1 x V2

Making V2 the subject:

 V2 = P1V1/4P1

        V2 = V1/4

<em>This means that the volume would change by being reduced to </em><em>1/4 </em><em>of the initial volume.</em>

Sarah measures out 151 grams of SO2. How many miles is this? Express your answer to three significant figures
elena-s [515]

150 g SO₂ = 2.36 mol SO₂

M_r = 32.06 + 2×16.00 = 32.07 + 32.00 = 64.06

Moles of SO₂ = 151 g SO₂ × [1 mol SO₂/64.06 g SO₂] = 2.36 mol SO₂
