(physical chemistry) An arrangement of bonds in a hyperconjugated molecule such that the number of bonds is the same in the two resonance structures but the second structure is energetically less favorable than the first structure; examples are H3CC+H2 and H3CCH2.

What is the difference between resonance and hyperconjugation?

What is meant by hyper conjugation in detail?
Hyperconjugation, otherwise known as Baker-Nathan effect, is the delocalisation of sigma electrons of C-H bond of an alkyl group directly attached to an atom of unsaturated system or to an atom with an unshared p-orbital. Stability of carbocations is based on hyperconjugative effect. Due to hyperconjugation, tertiary carbocation has 9 resonance structures, secondary carbocation 6 resonance structures, primary carbocation 3 resonance structures. Hence stability is tertiary>secondary>primary.
What are structures that have the same function but different structures called?
homologous structures
What does the word aliovalent mean?
The root word "valent" is referring to the valence of an atom or ion. The prefix "alio" means different. Two aliovalent ions are ions that have a different valence. In other words they don't have the same number of valence electrons. The converse of this word would be "isovalent", meaning that the two ions are of the same valence.
Can freely rotate about the carbon bonds because they only have single bonds?
Single bonds allow free rotation. Free rotation may be hindered sterically (large substituents that "bang" into one another " or due to hyperconjugation as in rotation barrier in ethane.
What is an isovalent resonance structure?

Is there any mnemonic for spectrochemical series?
Yes there is a mnemonic for the spectrochemical series. It is: "C.B.A.S.E.F.A.G.H.I". This acronym stands for the following order: C - Cation B - Base A - Acid S - Strong E - Electropositive F - Formation A - Anion G - Group H - Hyperconjugation I - Inductive Effect. C - Cation B - Base A - Acid S - Strong E - Electropositive F - Formation A - Anion G - Group H - Hyperconjugation I - Inductive EffectBy remembering this mnemonic you can easily recall the order of the spectrochemical series.

Similar structures that related species have inherited from a common ancestor are called structures?
Homologous structures.

What are homologuos structures?
structures which are similiar
What are engineered structures?
engineered structures are the structures which can withstand natural disasters such as earthquakes etc.
