Which orbital hybridization change occurs when methane (CH4) reacts to form chloroform (CHCl3)?

💡 Explanation

When methane is halogenated to form chloroform, the central carbon atom remains tetrahedrally bonded with four sigma bonds, involving four sp3 hybrid orbitals from the carbon overlapping with s orbitals of hydrogen or chlorine. Therefore no change occurs in hybridization, rather than other hybridization changes which are associated with different geometries and bonding arrangements.
