Resonance effect is called conjugative effect if it is transmitted through whole of the conjugated system

Describe resonance effect with one example.

Among the following which one is having conjugated system :

Mesomeric or resonance effect is a permanent effect involving the transfer of electrons relayed through pi electrons of multiple bonds or a lone pair of electrons and multiiple bonds in a chain of carbon atoms in a molecule

Which among the following statements are true with respect to electronic displacement in a covalent bond? I) Inductive effect operates through a pi- bond II) Resonance effect operates through a sigma- bond III) Inductive effect operates through a sigma- bond IV) Resonance effect operates through a pi- bond V) Resonance and inductive effects operate through a sigma- bond

Hyperconjugation effect is also termed as 'no bond resonance'. Why?

What are factors effect the nervous system?

The delocalisation of sigma electrons with P-orbital is known as Hyperconjugation. It is also known as sigma-pi conjugation 'or' No bond resonance. Presence of atleast one 'alpha' hydrogen at saturated carbon in an alkene, carbocation and free radical involves hyper conjucation. More is the no. of hyper conjugative structures more stable is the alkene. Bond lengths, dipolemoments are also effected by hyperconjugation. Hyper conjugation involves the
