In a methane (CH4) molecule, the four C-H bonds are equivalent and tetrahedral. What is the total sum of all H-C-H bond angles in degrees?
Q1. In a methane (CH4) molecule, the four C-H bonds are equivalent and tetrahedral. What is the total sum of all H-C-H bond angles in degrees?
Answer: 657.0
Explanation: A tetrahedron has six H-C-H bond angles of 109.5 degrees each, totaling 657 degrees. 438 only accounts for four angles.
