Question

Show the structures of alkenes that give the following products on oxidative cleavage within acidic solution:

Short answer

1. But-1-ene.

Step-by-step solution

Oxidation by KMNO4

${\mathbf{KMNO}}_{\mathbf{4}}$is called potassium permanganate. It isa solid oxidising agent.

Oxidative cleavageleads to the formation of 1,2-diol, which leads to the construction of carboxylic acid,which changes the color of to brown.

The colour changes from purple to brown, and diol leads to producing two adjacent alcoholic groups.

It is also one of the tests to detect the presence of a double bond in the compound or distinguish between saturated and unsaturated compounds.

Structure of alkene undergo oxidation

But-1-ene is the alkene thatundergoes oxidation with potassium permanganate leading to the breakdown of double bond to form 1,2 diol, which on further oxidation includes carboxylic acid,andreleases the carbon dioxide and water.

Product formation

1. Formation of

The reaction that follows is given below.
