Identify the product formed when $cis-but-2-ene$ reacts with $Baeyer's$ reagent (cold,dilute alkaline $KMnO_4$ solution).

What is the product obtained from the reaction of propene with $HCl$,$HBr$,and $HI$ in the presence of peroxide?

Alkene $(A)$ will be:
$\mathop A\limits_{(\text{alkene})} \xrightarrow{RCO_3H, H_2O} \text{Racemic mixture}$
$\mathop A\limits_{(\text{alkene})} \xrightarrow{\text{Cold dil. } KMnO_4} \text{Meso-compound}$

$6 \ L$ of an alkene require $27 \ L$ of oxygen at constant temperature and pressure for complete combustion. The alkene is.....

Which reaction has the lowest $\Delta G^{\ddagger}$ (Activation Energy)?

Identify the major product $X$ in the following dehydration reaction: $(CH_3)_3C-CH(OH)-CH_3 \xrightarrow{H_2SO_4} X$.
