Which of the following reagents is used to prepare $Propan-1-ol$ from $propene$?

The conversion of $2,3-$dibromobutane to $2-$butene using $Zn$ and alcohol is a/an .... reaction.

Which of the following alkenes does $\underline{NOT}$ exhibit cis-trans isomerism?

$HCl$ 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?

On reaction with hot conc. $H_2SO_4$,which one of the following compounds loses a molecule of water?

Identify the product of the following reaction: $CH_3-CH=CH-CH_3 \xrightarrow[(ii) H_2O, Zn]{(i) O_3} \text{Product}$
