$^{14}CH_2=CH-CH_3 \xrightarrow[\text{or high temp}]{\text{low conc of } Br_2} (?)$
Product of the above reaction is

In the reaction $C_2H_5CH = CH_2 + H - X \rightarrow$ Product,what is the major product?

What is the product formed when $RCH = CH_2$ is treated with $B_2H_6$ followed by oxidation with alkaline $H_2O_2$?

An alkene $X$ $(C_6H_{12})$ on ozonolysis gives acetaldehyde and ethyl methyl ketone. What is the product formed when $X$ reacts with $HBr$?

The correct statement$(s)$ for the following addition reactions is(are):
$(i)$ $trans-but-2-ene \xrightarrow{Br_2/CHCl_3} M \text{ and } N$
(ii) $cis-but-2-ene \xrightarrow{Br_2/CHCl_3} O \text{ and } P$
[$A$] ($M$ and $O$) and ($N$ and $P$) are two pairs of diastereomers
[$B$] Bromination proceeds through trans-addition in both the reactions
[$C$] $O$ and $P$ are identical molecules
[$D$] ($M$ and $O$) and ($N$ and $P$) are two pairs of enantiomers

The intermediate during the addition of $HCl$ to propene in the presence of peroxide is
