Classify each reaction as undergoing "anti-markovnikov", "markovnikov", "non-zaitsev", or "zaitsev".

Reactions are shown below,

Reaction 1:
                  This reaction followed Morkovnikov's rule, because according to this rule hydrogen will go to that carbon which has greater number of hydrogens or fewer number of carbons.

Reaction 2:
                 This reaction followed Anti-Morkovnikov's rule, and it is opposite to reaction 1.

Reaction 3:
                 This reaction followed Zaitsev's Rule, according to this rule elimination will yield highly substituted alkene.
