Which of the following is not a property of diborane?
It is highly reactive towards water.
It is a reducing agent.
It is a Lewis acid.
It is a strong oxidizing agent.
Diborane is a highly reactive and versatile molecule, but it is not a strong oxidizing agent. It is a reducing agent, which means that it can donate electrons to other molecules and reduce their oxidation state. It is also a Lewis acid, which means that it can accept a pair of electrons from a Lewis base. Additionally, diborane is highly reactive towards water and can undergo hydrolysis to produce boric acid. Hence option D is the correct answer.
Option(A) diborane is highly reactive towards water and can undergo hydrolysis to produce boric acid. Hence option A is incorrect.
Option(B) It is a reducing agent, which means that it can donate electrons to other molecules and reduce their oxidation state. Hence option B is incorrect.
Option(C) It is also a Lewis acid, which means that it can accept a pair of electrons from a Lewis base. Hence option C is incorrect.
