Halohydrin formation reaction

The basic chemical equation for this reaction is as follows:

C=C + X₂ in H₂O --> X-C-C-OH

(X represents a halogen, either Cl or Br).

The reaction occurs with anti addition[?], leaving the newly added X and OH groups trans[?] to each other.

The reaction is a form of electrophilic addition[?].

In the first step, a halogen attacks the pi bond[?] of the carbon-carbon double bond[?], forming a single bond to each of the two carbons. Then an H₂O molecule bumps into the slightly positively charged carbon atom that results from step one, bonding before the negative halogen atom left over can bond. The oxygen at this point has three bonds and a positive formal charge[?]. Another water molecule happens by quickly enough to escort off the extra H ion, leaving the final product.
