When ethene reacts with bromine,it forms

For the preparation of alkenes,an aqueous concentrated solution of sodium or potassium salts of carboxylic acids is subjected to ........

The reaction of propene with $Cl_2$ at $400-600\,^oC$ gives...........

Arrange the following alkenes in decreasing order of stability. Choose the correct answer from the options given below:

The reaction of $CH_3-CH=CH_2$ (propene) with $HI$ gives isopropyl iodide instead of $n$-propyl iodide because:

In the given reaction $x$ is: $CH_3 - C \equiv CH$ $\xrightarrow{\text{Excess } HCl} (A)$ $\xrightarrow{H_2O/OH^{-}} (x)$
