$H_2O_2$ on reacting with ethene gives:

Find the product of the reaction: $CH_3 - CH = CH_2 + HBr \rightarrow$ ?

The product obtained by the reaction of $1,2$-dibromoethane with zinc metal at high temperature is........

In the given reaction,what will be the structure of $Z$?

Arrange $HI$,$HCl$,$HBr$,and $HF$ in increasing order of rate of reaction with alkene.

Peroxide effect is observed with the addition of $HBr$ but not with the addition of $HI$ to unsymmetrical alkene because
