SUMMARY

The bond angle of 109 degrees in the antidote molecule is attributed to the tetrahedral geometry resulting from sp3 hybridization of the carbon atom. This configuration arises when four atoms are bonded to a central carbon atom, leading to the characteristic bond angle. The tetrahedral shape minimizes electron pair repulsion, establishing the 109.5-degree angle, which is commonly approximated as 109 degrees in discussions.

PREREQUISITES
  • Understanding of sp3 hybridization
  • Knowledge of molecular geometry
  • Familiarity with electron pair repulsion theory
  • Basic concepts of bond angles in chemistry
NEXT STEPS
  • Research the concept of sp3 hybridization in detail
  • Explore molecular geometry and its implications in organic chemistry
  • Study the VSEPR theory for predicting molecular shapes
  • Investigate the effects of lone pairs on bond angles
USEFUL FOR

Chemistry students, educators, and anyone interested in molecular geometry and hybridization concepts.

Homework Statement


Please refer to the image

Why is y 109 degrees?(given by my teacher)


Homework Equations


None.


The Attempt at a Solution


There are four atoms around the carbon atom, I assumed it to be tetrahedral.

Why is that wrong?
