Consider the given chemical reaction:
$Cyclohexene \xrightarrow[Heat]{KMnO_4, H_2SO_4} \text{Product } A$
Product $A$ is:

The product $A$ of the following reaction is:
$R_2C=CHR' \xrightarrow[Zn/H_2O]{O_3} A$

In the given compounds,which one does not give glyoxal $(CHO-CHO)$ as one of the products on ozonolysis?

Consider the following sequence of reactions: $CH_3-CH=CH_2$ $\xrightarrow[700\,K]{Cl_2} A$ $\xrightarrow[420\,K, 12\,atm]{Na_2CO_3} B$ $\xrightarrow[(ii) NaOH]{(i) HOCl} C$. Compound $C$ is:

For the reaction $CH_3-CH=CH_2 + HOCl \to A$,the product $A$ is:

Addition of $BH_3$ followed by $H_2O_2$ to $trans-2-butene$ would give a product which is
