When $CH_2=CH-COOH$ is reduced with $LiAlH_4$,the compound obtained will be:

For the following reactions,the major products are shown: $H_2C=CH-CH=CH_2$ $\xrightarrow[0^\circ C]{HBr} CH_2=CH-CH(Br)-CH_3$ $\xrightarrow{25^\circ C} Br-CH_2-CH=CH-CH_3$. These provide an example of $1$ control at low temperature and $2$ control at higher temperature.

On catalytic reduction $(H_2/Pt)$,how many alkenes will give $2-$methylbutane?

In the presence of peroxide,$HCl$ and $HI$ do not give anti-Markownikoff's addition to alkenes because

Write a test to detect the presence of a double bond in a molecule.

The reaction of ethene with oxygen in the presence of a silver catalyst gives ....................
