Which of the following molecule act as only Lewis acid ? (CH3)3N(CH3)3B(CH3)2O(CH3)3P
Question
Which of the following molecule act as only Lewis acid ? (CH3)3N(CH3)3B(CH3)2O(CH3)3P
Solution
A Lewis acid is a chemical species that can accept a pair of electrons.
Among the given options, (CH3)3B, also known as trimethylborane, acts as a Lewis acid. This is because boron in trimethylborane has only six electrons in its valence shell, and it can accept a pair of electrons to complete its octet, thus behaving as a Lewis acid.
So, the correct answer is (CH3)3B.
