Question
According to Lewis acid-base theory, which of the following is least likely to act as a Lewis acid?
Answer: B
💡 Solution & Explanation
A Lewis acid is an electron pair acceptor (electrophile). $BF_3$, $AlCl_3$, and $SnCl_4$ have empty orbitals. $PF_3$ has a lone pair on phosphorus, making it act primarily as a Lewis base (electron pair donor).
