Book Free Demo1. Which of the following hydrocarbons undergo addition reactions:
\(C_2H_6\), \(C_3H_8\), \(C_3H_6\), \(C_2H_2\) and \(CH_4\).
\(C_2H_6\), \(C_3H_8\), \(C_3H_6\), \(C_2H_2\) and \(CH_4\).
Alkenes and alkynes undergo addition reactions because they are connected by or bonds and are unsaturated hydrocarbons. From the above hydrocarbons, \(C_2H_2\) (acetylene) is an alkyne, whereas \(C_3H_6 \) (Propyne) is an alkene. So, \(C_3H_6 \) and \(C_2H_2\) will undergo addition reactions.
2. Give a test that can be used to differentiate chemically between butter and cooking oil.
, or the addition of hydrogen, is a chemical test to differentiate between butter and cooking oil.
Butter contains saturated fats. Hence, it cannot be hydrogenated. On the other hand, the oil contains fats. That is why it can be hydrogenated to saturated fats (solids).
