Q. 12.57 - An Introduction to General, Organic, and Biological Chemistry

Question

Draw the condensed structural or line angle formula ,if cyclic. for each of following:

(a) $4 chlorobenzaldehyde$

(b) $3 chloropropionaldehyde$

(c) $Ethyl methyl ketone$
(d) $3 methyl hexane$

Step-by-Step Solution

Answer

Line angle formula corresponding to given compounds are:

1.  $4-$chlorobenzaldehyde:
2.  $3-$ chloropropionaldehyde:
3. Ethyl methyl ketone:
4. $3$ methyl hexane:

Part (a) Step 1: Given Information

We need to find structural and line formula of $4-$chlorobenzaldehyde

Part (a) Step 2: Explanation

Compound $4-$chlorobenzaldehyde is benzene with functional groups present at position $1$ and $4$. As chlorine group is having less priority than aldehydic group. So chlorine is at $4$ position.

The structure of $4-$chlorobenzaldehyde is

Part (b) Step 1: Given Information

We need to find structural and line formula of $3-$chloropropionaldehyde

Part (b) Step 2: Explanation

Compound $3-$chloropropionaldehyde is straight chain three carbon atom compound with an aldehydic group present as functional group and chlorine as substituent at $3^{rd}$ position.

The structure of $3-$chloropropionaldehyde   is 

Part (c) Step 1: Given Information

We need to find structural and line formula of ethyl methyl ketone.

Part (c) Step 2: Explanation

Compound ethyl methyl ketone  is ketone whose IUPAC name is $2-$butanone. So it is straight chain compound of $4$ carbon atoms having ketonic group at second position.

So, the structure of ethyl methyl ketone is 

Part (d) Step 1: Given Information

We need to find structural and line formula of given compound.

Part (d) Step 2: Explanation

Compound  $3-$methyl hexanal is straight chain compound of six carbon atoms having methyl as substituent at third position.

So, structure of $3-$methyl hexanal is
