What is the hybridization of C in co2 and CHCl3?

Assuming all atoms are hybridized, the carbon and oxygen atoms are sp2 hybridized, and the two chlorine atoms are sp3 hybridized.

What is the geometry of CHCl3?

According to the VSEPR theory, the CHCl3 molecule possesses tetrahedral molecular geometry. Because the center atom, carbon, has three C-Cl and one C-H bonds with the three chlorine and one hydrogen atoms surrounding it. The Cl-C-H bond angle is 109.5 degrees in the tetrahedral CHCl3 molecular geometry.

What is the type of hybridisation of each carbon in the following compounds CH3Cl?

sp3 hybridised
