Lewis base Correct A Lewis acid is an electron pair acceptor. B has an incomplete octet in BF, and, as an electron deficient species, is an electron pair acceptor in the reverse reaction, so Lewis acid. bis (CH), a Lewis acid or a Lewis base? Lewis acid • Lewis base Correct A Lewis bus is an electron pair donor. The batom in (CH), has two lone pairs and is an electron pair donor in the reverse reaction, so (CH), is a Lewis base If you place 1.0 g of the complex in a 63.5 ml flask at 125 "C, what is the total pressure in the task at equilibrium? What are the partial pressures of the Lewis acid, the Lewis base, and the complex P(BF) - P(CH),0) am PCH), O DP.) P(total) atm

Answer 1
