Propene has three electron groups surrounding the core carbon atom, as seen in the Lewis dot structure of the compound.

<h3>What is Lewis dot structure?</h3>

A Lewis Structure is a greatly condensed illustration of a molecule's valence shell electrons. It is used to display how the electrons are positioned around particular molecules' atoms. When two atoms are bonded together, electrons are depicted as "dots" or as a line.

Lewis structures, often referred to as Lewis dot formulas, electron dot structures, or Lewis electron dot structures, are diagrams that depict the interactions between the atoms in a molecule as well as any lone pairs of electrons that may be present.

How many co2 molecules would be formed from the reaction mixture that produces the greatest amount of products?

bezimeni [28]

<h2>Answer : 2 molecules of $CO_{2}$ will be formed.</h2><h3>Explanation :</h3>

Considering the reaction as

$2CH_{3}OH_{(g)}+3O_{2}_{(g}$ -----> $2CO_{2}_{(g)}+4 H_{2}O_{(g)}$

Here, 2 molecules of methyl-alcohol combines with 3 molecules of oxygen to give 2 molecules of $CO_{2}$ and 4 molecules of $H_{2}O$ .

If 1 molecule of methanol is used then only one carbon dioxide molecule will be produced. But as per the given reaction two moles of methanol will produce 2 moles of carbon dioxide molecules.
