Bromination of cyclohexene under the conditions given below yields:
Cyclohexene $\xrightarrow{Br_2/hv}$ ?

$HCl$ does not show the peroxide effect because the reaction mechanism involves the following steps:
$CH_3-CH=CH_2 + \dot{X} \to CH_3-\dot{C}H-CH_2X$ $(I)$
$CH_3-\dot{C}H-CH_2X + HX \to CH_3-CH_2-CH_2X + \dot{X}$ $(II)$
Why does $HCl$ fail to undergo this reaction?

Arrange the following compounds in the order of their reactivity towards electrophilic addition reaction with $HBr$.

Suppose the following reaction,the major product will be:

Which method can be used to prepare $Propane$ from $Propene$?

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