Answer:

Typically this is the addition of #HX# #(X=Cl, Br, I)# to an olefin, #R-CH=CH_2#...

Explanation:

And the reaction follows the general scheme...

#R-CH-CH_2 + HX rarr underbrace(Rstackrel(+)CHCH_3)_"secondary carbocation" + X^-#

#Rstackrel(+)CHCH_3 + X^(-)rarrRCH(X)CH_3 #

This reaction follows so-called #"Markownikow selectivity"#,,the more substituted alkyl halide is favoured. Anyway, you are going to have to read your text...
