Non-conjugated β, γ-unsaturated ketones, such as 3-cyclohexenone, as in base-catalyzed equilibrium with their α,β-unsaturated is

omers. An interesting consequence of this isomerization of unsaturated ketones is that 2-substituted cyclopentenones, such as 2-methyl-2-cyclopentenone, can be interconverted with 5-substituted 2-cyclopentenones. The first intermediate in this reaction has three resonance structures.
Draw all resonance structures for the first intermediate in the conversion of 2-methyl-2-cyclopentenone to 5-methyl-2-cyclopentenone.

Which diagram shows a wave with the highest frequency? Chemistry question.
notsponge [240]

The correct answer is D

Explanation:

Wave frequency is mainly determined by the number of waves that pass through a specific point. In a diagram, this can be found by analyzing the number of crests (top of the wave) and the space between them. For example, wave B is the one with the lowest frequency because there is only one crest and this shows only one wave passing at a specific point. On the opposite, wave D is the one with the highest frequency because this shows multiple crests and this indicates the frequency is high or that many waves pass through a specific point in a short time.

5) What is the difference between CO2 and XeCl2? The difference between SCl2, SCl4, and SCl6?
nadezda [96]

CO₂ has 4 + 2(6) = 16 valence electrons

CO₂ have linear molecular structures with a 180° bond angle. CO₂ is nonpolar  because the individual bond dipoles cancel each other out

XeCl₂ has 8 + 2(7) = 22 valence electrons.

There are five pairs of electrons about the central Xe atom. The structure will be based  on a trigonal bipyramid geometry. The most stable arrangement of the atoms in XeCl₂ is  a linear molecular structure with a 180° bond angle. It is nonpolar because the Xe−Cl bond dipoles  and lone pairs around Xe are arranged in such a manner that they cancel each other out.

(b)

SCl₆ is nonpolar because it has 6 bonding pairs and no lone pairs, giving it an octahedral shape. When you draw the vectors, you can see that the resultant is 0, making it nonpolar.

SCl₄ on the other hand is polar because it has 4 bonding pairs and one lone pair, giving it a trigonal pyramidal shape.

SCl₂ is also polar due to reasons similar to those in the case of SCl₄.

A substance with a pH value of 8.0 and [H3O+] of 1.00 x 10-8 would be a basic substance.
garik1379 [7]
False

if the pH is 8, this is basic because based on the pH scale, any below 7 is acidic, above 7 is basic and at 7 is neutral.
