Answer
Electron geometry: tetrahedral
Molecular geometry: tetrahedral
Idealized bond angle: $109.5^{\circ}$
Deviation from idealized bond angle : yes
Work Step by Step
$CHCl_3$ has 3 covalent bonds between C and Cl atoms, an one covalent bond between the C and H atom. Its electron geometry is tetrahedral. Its molecular geometry is also tetrahedral since C atom is bonded to 4 other atoms. Its idealized bond angle is that of the tetrahedral geometry, $109.5^{\circ}$. But the large size of Cl atomsas compared to the H atom causes deviation from the idealized bond angle.
