For the reaction pathway below, what are the names for the first and second steps?

$${\text{C}}{{\text{H}}_{\text{2}}}{\text{CHC}}{{\text{H}}_{\text{3}}} \to {\text{C}}{{\text{H}}_{\text{3}}}{\text{CHClC}}{{\text{H}}_{\text{3}}} \to {\text{C}}{{\text{H}}_{\text{3}}}{\text{CHOHC}}{{\text{H}}_{\text{3}}}$$
