With oxalic acid,glycerol at $260\,^\circ C$ gives

$CH_3-CH_2-CH_2-Br$ $\xrightarrow{\text{alk. KOH}} A$ $\xrightarrow[(ii) H_2O_2/OH^{-}]{(i) BD_3/THF} B$; $B$ is:

The reaction of ethene with $Cl_2$ in a saturated solution of $KBr$ yields:

Give the order of stability for different alkenes.

An unknown alkene $(A)$ reacts with $3 \ mole$ of $H_2$ gas in the presence of a platinum catalyst to form $1$-isopropyl-$4$-methylcyclohexane. When the unknown alkene $(A)$ is ozonized and reduced,the following products are obtained:
$HCHO$,$OHC-CH_2-CO-CO-CH_3$,and $CH_3-CO-CH_2-CHO$
What is the structure of alkene $(A)$?

$A$ hydrocarbon having molecular formula $C_5H_{10}$ produced a tertiary alcohol upon treatment with a few drops of conc. sulphuric acid and water. The same hydrocarbon when reacted with acidic potassium permanganate produced a ketone and a carboxylic acid. The hydrocarbon is $....$
