Using molecular orbitals, determine if the following cycloaddition of 1,3-butadiene and allyl anion is thermally allowed. heat ?

ASHA 777 [7]3 years ago
4 0

Answer: cycloaddition of 1,3-butadiene and allyl anion is thermally allowed.

Explanation:

Using the frontier molecular orbital approach, we consider if the symmetry of the LUMO of the diene (1,3-cyclobutadiene) and the HOMO of the dienophile allyl anion), match each other since the diels alder reaction is a symmetry allowed process. The symmetries of these frontier molecular orbitals match each other hence the reaction is thermally allowed. It should be notes that 4+2 cycloadditions are thermally allowed although they are slow.

sergejj [24]

Answer:

The temperature of the gas.

Explanation:

According to the kinetic molecular theory, the molecules of a substance are in constant random motion.

If an ideal gas is contained is a sealed rigid container, the average velocity of the gas molecules is dependent of the temperature of the gas.

Recall that temperature is defined as the average kinetic energy of the molecules of a body.

State and explain the observations when chlorine gas is bubbled through a solution of
natta225 [31]

Answer:

A reduction-oxidation (redox) reaction will occur.

Chlorine gas (Cl2) will accept electrons to form Cl- ions.

The Iron(II) ions (Fe2+) will lose electrons to form Fe3+ ions. (Iron (III) ions)

Fe2+ ions are green, while Fe3+ ions are yellow,

so the observation will be the solution turning from green to yellow.
