The TLC analysis is aimed to verify the completion and the product of the reaction. potassium permanganate is then added to the TLC plate to detect the existence of double bond in the final product. Potassium permanganate reacts with the double bond and makes the spot yellow-brown.
Electrophilic addition is an exothermic reaction, in which a pi bond is turned into a sigma bond. The double bond in the alkene acts as a nucleophile. Halogens, halogen acids , hypohalous acids, sulphonic acid and water can be used as the electrophilic reagent. In this experiment, bromination of cholesterol is performed. The electrophilic attack of Br2generates acyclic bromonium ion. The addition gives a trans stereochemistry to the bromonium ion. As the Br-attacks the most substituted carbon in anti-periplanar fashion by SN2reaction, it would result in the inversion of configuration at that specific carbon.

Answer:
Both extensive and intensive properties are physical properties, which means they can be measured without changing the substance's chemical identity. For example, the freezing point of a substance is a physical property: when water freezes, it's still water (H2O)—it's just in a different physical state.
Explanation:
Answer:
the limiting reagent is butane
