Hyperconjugation is also known as

  1. Aelectromeric effect
  2. Binductomeric effect
  3. Cmesomeric effect (+M)
  4. Dno-bond resonance

Answer: D

Delocalisation of sigma electrons of an alpha C-H bond into an adjacent pi system or empty p orbital is drawn with structures having no bond between C and H. Hence it is called no-bond resonance (Baker-Nathan effect).
