The correct stability order of alkyl substituted alkenes is

Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R.$
Assertion $A :$ Treatment of bromine water with propene yields $1-$bromopropan$-2-$ol.
Reason $R:$ Attack of water on bromonium ion follows Markovnikov rule and results in $1-$bromopropan$-2-$ol.
In the light of the above statements,choose the most appropriate answer from the options given below:

Which of the following reactions proceeds via a secondary free radical?

In the presence of peroxide,hydrogen chloride and hydrogen iodide do not give anti-Markovnikov addition to alkenes because:

Write the products of the addition reaction $ >C = C < + XY \to $

Which of the following acids adds to propene in the presence of peroxide to give anti-Markownikoff's product?
