Which of the following does not undergo anti-Markovnikov addition of HBr?

Baeyer's reagent is: 

1. Acidified permanganate solution

2. Alkaline permanganate solution

3. Neutral permanganate solution

4. Aqueous bromine solution

Consider the following reaction,

The structure of the major reaction intermediate formed in the above reaction is-

 1-Butyne and 2-Butyne can be differentiated by:

1. Bromine, CCl₄

2. H₂ , Lindlar catalyst

3. Dilute H₂SO₄, HgSO₄ 

4. Ammoniacal cuprous chloride

In the presence of peroxide, hydrogen chloride and hydrogen fluoride do not undergo anti-Markovnikov's

addition reaction with alkenes because-

1. Both are highly ionic

2. One is oxidizing and the other is reducing

3. One of the steps is endothermic in both the cases

4. All the steps are exothermic in both cases

The reaction of propene with HOCl proceeds via the addition of:

The compound among the following that yield propyne on hydrolysis is:

2. ${\mathrm{Mg}}_2{\mathrm{C}}_3$

3. ${\mathrm{B}}_4\mathrm{C}$

4. ${\mathrm{La}}_4{\mathrm{C}}_3$

The reaction of HBr with 

 in the presence of peroxide will give:

1.
2.
