Include all steps of reaction, any additional reagents/conditions needed and the products formed.
ive been stuck on this for hours need help please
I think this will answer your questions. There are a number of possible products depending upon the conditions of the oxidation. Here is a site that gives all of the possibilities.

Note: What is called potassium manganate(VII) in the link above is KMnO4, also known as potassium permanganate.
The reaction you mentioned is known as the oxidative cleavage of an alkene using potassium permanganate (KMnO4). To understand the reaction and its steps, let's break it down:
Step 1: Determine the type of reaction
This reaction involves the oxidative cleavage of an alkene. Oxidative cleavage refers to breaking the double bond (alkene) and introducing oxygen atoms (oxidation) into the carbon backbone.
Step 2: Write the balanced chemical equation
The given alkene is CH3CH2CH=CHCH3. When potassium permanganate (KMnO4) is used as the oxidizing agent, it undergoes reduction itself. The balanced equation for the reaction is:
CH3CH2CH=CHCH3 + 2KMnO4 + 3H2O ->
Step 3: Determine the products
In this reaction, the alkene is cleaved into two separate fragments. Each carbon-carbon double bond is broken, resulting in two functional groups: ketones (C=O) and carboxylic acids (COOH).
The products formed can be identified by splitting the alkene and adding two oxygen atoms to each carbon atom.
So, the products formed are:
1. A ketone: CH3CH2C(=O)CH3
2. A carboxylic acid: CH3CH2COOH
Step 4: Determine the additional reagents/conditions
In the reaction, the major reagent used is potassium permanganate (KMnO4). Potassium permanganate is a strong oxidizing agent that provides oxygen atoms to the alkene to facilitate the oxidative cleavage. In some cases, acidic conditions are required to carry out this reaction.
So, the complete reaction with all its steps and products is:
CH3CH2CH=CHCH3 + 2KMnO4 + 3H2O -> CH3CH2C(=O)CH3 + CH3CH2COOH
Please note that the reaction conditions (temperature, concentration of reagents, etc.) can vary depending on the specific situation, so it's always important to consult the experimental details or any specific instructions provided.
