How many electrons does a single oxygen gain or lose in the following reaction?
REY [17]

Answer:

it gains 2 electrons

Explanation:

atoms want to be more stable, for oxygen it's number is 8, 2 less than the stable ring of 10. and hydrogen has a single electron, 1 less than the stable ring of 2. so oxygen takes 2 electrons 2 make it stable and hydrogen becomes attatched to the oxygen atom to form a covalent bond

The average bond order is the number of bonds between two atoms taking into account resonance.
Gemiola [76]

1. Sulfur dioxide, or SO2 , has two resonance structures which contribute equally to the overall hybrid structure of the molecule. However, a third Lewis structure can be drawn for SO2 which is more stable in theory, but doesn't quite match experimental data.

2.

\color{red} = \frac{No.  \: of  \: bonding  \: electron  \: pairs}{No.  \: of  \: bonded \: atoms}

In  \: each  \: resonance  \: contributor, \\  there  \: are \:  six \: bonding  \: electron  \\ pairs \:  and  \: four  \: atoms  \: bonded  \\ to \:  the  \: SS  \: atom.  \: Thus,

BO =  \frac{6}{4}  = 1.5

As a Ca atom undergoes oxidation to Ca2+, the number of neutrons in its nucleus
maria [59]
Oxidation refers to a change in electrons (In this case, loss of electrons). It has no impact on the number of neutrons, or for that matter on any sub-atomic particles in the nucleus. So the number of neutrons (3) remains the same

What would be the product if dimethyl maleate was heated in the presence of 3-sulfolene?
prisoha [69]

An organic reaction between a substituted alkene and a conjugated diene to form a substituted cyclohexene derivative is said to be Diels-Alder reaction (specifically, [4+2 cycloaddition). The formation of new \sigma-bonds is the driving force of this reaction, which is energetically more stable than the \pi-bonds.

The reaction that takes place due to the heating of dimethyl maleate in presence of 3-sulfolene is as shown in the image.

On heating 3-sulfolene the compound breaks down to give sulfur dioxide gas and butadiene. This diene then reacts with dimethyl maleate which acts as a dienophiles and then these two diene and dienophiles will undergo a Diels-Alder reaction to form a new 6-membered cyclohexene ring.

Thus, the product formed due to the heating of dimethyl maleate in presence of 3-sulfolene is dimethyl cyclohex-4-ene-1,2-dicarboxylate.
