Question

1)The Bond angle between carbon atoms in cyclohexaneis​

Answer 1

Explanation:

The actual normal value for the C-C-C bond angle of an open-chain −CH2−CH2−CH2 unit appears to be about 112.5°, which is 3° greater than the tetrahedral value. From this we can conclude that the angle strain at each carbon of a planar cyclohexane would be (120° — 112.5°) = 1.5°.

Answer 2

The C-C-C bond angles are ~111o and the H-C-H bond angles are correspondingly smaller (107o) than the ideal sp3 bond angle of 109.5o present in methane.
