Problem: Write the Lewis structures of the reactants and product of each of the following equations, and identify the Lewis acid and the Lewis base in each:(a) CS2 + SH− ⟶ HCS3−

FREE Expert Solution

We’re being asked which of the given compounds is a Lewis acid and Lewis base

Let’s first define a Lewis acid and a Lewis base.


Based on the Lewis definition:

Lewis acid is an electron pair acceptor.

Some characteristics of a Lewis acid:

When hydrogen is connected to an electronegative element such as P, O, N, S or halogens

▪ hydrogen gains a partially positive charge → makes hydrogen act as a Lewis acid

Positively charged metal ions
