#### Answer

$C_1$
Hybridization: $sp^3$
Geometry: tetrahedral
Bond Angels: 109.5
$C_2$
Hybridization: $sp^2$
Geometry: Trigonal Planar
Bond Angels: 120
$C_3$
Hybridization: $sp^2$
Geometry: Trigonal Planar
Bond Angels: 120
$C_4$
Hybridization: $sp^3$
Geometry: tetrahedral
Bond Angels: 109.5

#### Work Step by Step

The $C_1$ and $C_4$ have four domains (four single bonds with H) around them. Thus, it's tetrahedral and tetrahedral geometry has 109.5 degrees angels.
The $C_2$ and $C_3$ have three domains (two single bonds and one double bond) around them. Thus, it's trigonal planar and trigonal planar geometry has 120 degrees angels.
