What is the angle between c-c sp3 structure

Question

IN TERAHEDRAL SHAPE

Answer 1

109.5 degree

Answer 2

108.28

Answer 3

108 deg 28"

Answer 4

Cos^-1(-1/3) = 109d 28' 16.3" (= 180d- 70d 31' 43.61")= 1.91063 Radians.

It is the regular Tetrahedral angle.

(In 2 dimensional triangle it is Cos^-1(-1/2); 4dimensional counterpart of tetrahedron the angle is Cos^-1(-1/4)).

Answer 5

sp3 is a tetrahedral, like you said.  Tetrahedrals have angles of 109.5 degrees.

Answer 6

It's the inverse cosine of -1/3. Which turns out to be about 109.47 degrees. If you forget, you can calculate it yourself again...

Answer 7

     in the sp3 hybridisation of C-C then the bond angle is 109.5 degree.
