Loss of any existing chirality....

Explanation:

Suppose we start with homochiral #H_3C-stackrel"*"CHBrCH_2CH_3#...the starred carbon is chiral....and a bond-breaking mechanism, which proceeds by a three-coordinate carbocation CANNOT support or transfer the chirality.

And thus hydrolysis (for instance) would lead to a racemic secondary alcohol....#H_3C-CH(OH)CH_2CH_3#.
