Question

Match: Substance Lewis base Bronsted-Lowry acid Arrhenius base Definition A. Provides H in water B. Provides OH in water C. Proton donor D. Proton acceptor E. Electron pair donor F. Electron pair acceptor

Answer 1

1. Sol :-

# Lewis base = (E) Electron pair donor

# Bronsted-lowry acid = (C) Proton donar

# Arrhenius base = (B) Provide OH^-

2.

# Lewis acid = Fe³⁺ , H⁺ , because they are electron pair acceptor.

# Lewis base = F^- , have tendency to accept a proton by giving electrons pair i.e. it is Electron pair donor.

# Can act as either Lewis acid = CN^-, because it act as a π-acceptor and σ-donar.

# Neither a Lewis acid or Lewis base = CH₄
