In the reaction below, how many grams of h2o(g) are produced when 2.1 grams o2(g) are consumed? c4h6(g) + o2(g) → co2(g) + h2o(g

amm1812

The balanced equation that illustrates the reaction is:
2C4H6 + 11O2 ......> 8CO2 + 6H2O

number of moles = mass / molar mass
number of moles of oxygen = 2.1 / 32 = 0.065625 moles

Now, from the balanced equation, we can note that:
11 moles of oxygen are required to produce 6 moles of water.
Therefore:
0.065625 moles of oxygen will produce:
(0.065625*6) / 11 = 0.03579 moles of water

number of moles = mass / molar mass
mass = number of moles * molar mass
mass of water = 0.03579 * 18 = 0.644 grams

Which of the following is the requirement for the intramolecular Sn2 reaction (intramolecular William Ether Synthesis) to occur

balandron [24]

Answer:

D. Anti-periplanar

Explanation:

In the second step of the intramolecular William Ether Synthesis mechanism (figure 1) we will have the attack of the negative charge of the oxygen to the carbon bond to the Br. At the same time the Br leaves, so a bond would be broken (the C-Br bond) and a bond would be formed (the C-O bond).

Now, this process can happen only if the attack and the leaving group has an anti configuration (figure 2). In an anti configuration the nucleophile and the leaving group would have opposite directions.
