Chlorine trifluoride has 5 regions of electron density around the central chlorine atom (3 bonds and 2 lone pairs). This carbon right here is SP hybridized since it bonded to two atoms and this carbon right here is also SP hybridized. For an atom such as oxygen, we know that the 2s orbital is spherical, and that the 2p x, 2p y, and 2p z orbitals are dumbell-shaped and point along the Cartesian axes.
