Question

The following electrostatic potential diagrams represent $\mathit{C}{\mathit{H}}_{\mathbf{4}}\mathbf{,}\mathit{N}{\mathit{H}}_{\mathbf{3}}\mathbf{}\mathit{o}\mathit{r}\mathbf{}{\mathit{H}}_{\mathbf{2}}\mathit{O}$. Label each, and explain your choices.

Short answer

Answer

(a)represents $H_{\mathit{2}}O$

(b) represents $N{H}_{\mathit{3}}$

(c) represents $C{H}_{\mathit{4}}$

Step-by-step solution

Step 1. Analyzing figure (a)

In fig.(a) red part shows high electron density towards O, and the blue part shows low electron density towards H-atoms.

Step 2. Analyzing figure (b)

In fig.(b) high electron density is shown towards N-atom(red colour) and the rest three blue bulges show low electron density towards H-atoms.

Step 3. Analyzing figure (c)

In fig.(c) four low electron density regions representing 4 H-atoms and C-atom at the centre
