Identify the wrong statement for the following reactions:
$CH_3-CH(CH_3)-CH=CH_2 \xrightarrow{HBr} A$
$CH_3-CH(CH_3)-CH=CH_2 \xrightarrow{HBr + ROOR} B$

The major product of the reaction of $2-$butene with cold alkaline $KMnO_4$ is:

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

An organic compound $X$ with molecular formula $C_{11}H_{14}$ gives an optically active compound on hydrogenation. Upon ozonolysis,$X$ produces a mixture of compounds $P$ and $Q$. Compound $P$ gives a yellow precipitate when treated with $I_{2}$ and $NaOH$ but does not reduce Tollen's reagent. Compound $Q$ does not give any yellow precipitate with $I_{2}$ and $NaOH$ but gives Fehling's test. The compound $X$ is:

What is the product of Hydroboration-oxidation of but-$1$-ene?
