Why does allyl anion have only two resonance structures?

There are only two resonance structures of allyl anion with negative charge distributed over positions 1 and 3: $$\ce{\overset{-}{C}H2-CH=CH2 <-> CH_2=CH-\overset{-}{C}H2}.$$ What's the criteria ...

But what are anti-bonding pi-orbital? In search for an intuitive explanation [closed]

Imagine that you want to explain to an undergraduate why they have to to shade the pi-orbitals in a symmetrical way, i.e. dark on top (+), white on bottom (-) for two neighbouring pi-orbitals because ...

Why do we see complementary colors in UV/Vis Spectroscopy? [closed]

From what I read, a compound that absorbs visible light will produce a complementary color (using the color wheel), that can be seen. Why is this the case? Is it because, for example, if a molecule ...

Confused about identifying delocalized electron pairs in Isoniazid

I have to identify delocalized electron pairs in Isoniazid (pairs not shown in the image below): I know the nitrogen in the ring has a localized electron pair, since it already forms a pi bond. I'm ...

Are all lone pairs considered as π-electrons?

According to me, in methylenepyran 8 π-electrons are present as there are 3 double bonds. Therefore, 2 × 3 = 6 π-electrons and 2 π-electrons as one of the two lone pairs of oxygen will participate in ...

Why doesn't Silicon act as the basis of a class of compounds like Carbon is for organic compounds?

Carbon is the basis of organic materials in large part due to it's four valence electrons. Silicon also happens to have four valence electrons as well but does not serve as a basis for a large set of ...
