Markovnikov rule and anti - markovnikov rule class 11 & 12 organic chemistry

Markovnikov rule is applicable to

Assertion: -The addition of HCl to unsymmetrical alkenes in the presence of organic peroxides takes place against Markownikoff's rule. Reason :- 2^@ free radicals are more stable than 1^@ free radicals.

In the reaction with HCl , an alkene reacts in accordance with the Markovnikov's rule to give a product 1-chloro,1-methylcyclohexane. The possible alkene is

Chargaff' a rule states that in an organism:

Statement-1: Addition of HBr of CH_(2)=CH-NO_(2) follows anti-Markovnikoff's rule and Statement-2: Electron withdrawing NO_(2) group destabilizes carbocation on the adjacent carbon.

Which statement is true ? i . The product is ii. The product is iii. The reaction is called alkoxymercuration - demercuration ( a type of solvomercuration - demercuration ) . iv It proceeds via markovnikov addition addition, anti - addition of and ROH( a nucleophilc solvent ) and not rearrangement.

In the presence of peroxide addition of HBr to propene takes place according to anti Markownikoff's rule but peroxide effect is not seen in the case of HCl and HI. Explain.

Which of the following reactions follows Markovnikov's rule?
