Question

Write the structural formula of
(a) $\text{o-Ethylanisole}$
(b) $\text{p-Nitroaniline}$
(c) $\text{2,3-Dibromo-1-phenylpentane}$

Answer 1

(a) Step 1 : Structure of anisole
We know the structure of anisole is:

Step 2 : Structure of $\text{o-Ethylanisole}$
Now in anisole, at ortho position add ethyl $(-C_2{H}_5)$ group. So, the structure of $\text{o-Ethylanisole}$ is:

Final Answer:
The structural formula of $\text{o-Ethylanisole}$ is


(b) Step-1 : Structure of aniline
We know the structure of aniline is:

Step 2 : Structure of $\text{p-Nitroaniline}$
Now in aniline, at para position add nitro $(-N{O}_2)$ group. So, the structure of $\text{p-Nitroaniline}$ is:


Final answer:
The structural formula of p-Nitroaniline is


Step 1 : Structure of pentane
Pentane means five carbon saturated hydrocarbon. So, the structure of pentane is:



Step 2 : Structure of $1-\text{phenylpentane}$
Now in pentane, at $1^{st}$ position add phenyl $(-C_6{H}_5)$ group by removing one H atom from $1^{st}$ carbon. So, the structure of $1-\text{phenylpentane}$ is:


Step 3 : Structure of $\text{2,3-Dibromo-1-phenylpentane}$
Now in 1-phenylpentane, at 2nd and 3rd position add two bromo $(-Br)$ group by removing one - one $H$ atom from each carbon. So, the structure of $\text{2,3-Dibromo-1-phenylpentane}$ is:


Final answer:
The structural formula of $\text{2,3-Dibromo-1-phenylpentane}$ is
