Electrolysis of cold concentrated aqueous solution of potassium succinate yields:

Explain the preparation of alkene from alkyl halide via dehydrohalogenation in detail.

Arrange the following compounds in the order of their reactivity towards electrophilic addition reaction with $HBr$.

$6 \ L$ of an alkene require $27 \ L$ of oxygen at constant temperature and pressure for complete combustion. The alkene is.....

The major product of the following reaction is:

The alkene that will give the same product with $HBr$ in the absence as well as in the presence of peroxide is
