Introduction to Organic Chemistry
The field of chemistry which deals with the studies of reactions, structures, and properties of organic compounds that comprise carbon bonded through covalent bonding is organic chemistry. The studies regarding the structure of organic compounds could be…
Vinyl Group
Vinyl group is the name given to the functional group of -CH=CH2. It can be seen as an ethene molecule with one less hydrogen in number. Hence it is also called as ethenyl group at times.
Straight Chain Hydrocarbons
The requirement to identify each compound needs a richer number of words than informative prefixes like n and iso. The identification of organic molecules is made easier by the use of systematic nomenclature schemes. The organic chemistry nomenclature ha…
Unsaturated Hydrocarbon
Following are few examples of alkenes with their general molecular as well as their structural formulas:
Conjugated Compounds in Organic Chemistry
The delocalization of electrons in a molecule is called conjugation in organic chemistry. This delocalisation process of electrons leads to the shortenings or elongations of chemical bonds, but at the same time it causes changes in the chemical propertie…
Alpha Carbon And Alpha Protons
The carbon directly attached to the functional group in an organic molecule is referred to as the alpha carbon and the hydrogen attached to an alpha carbon are termed as the alpha hydrogens or alpha protons. These alpha carbon atoms and alpha hydrogen at…

Chapter 6, Problem 6.114EP

(a)

Interpretation Introduction

Interpretation:

Structural formula for N,N-diethylpropanamide has to be drawn.

Concept Introduction:

Structure of the amide can be drawn from the IUPAC name.  In the IUPAC name, the parent chain of carbon atom can be identified and then the substituents present in it can also be identified.  With this information, the structure for the given compound can be drawn.  In an amide the counting has to be always from the carbonyl carbon that is given the number 1.

The structural representation of organic compound can be done in 2D and 3D.  In two-dimensional representation, there are four types of representation in which an organic compound can be drawn.  They are,

  • Expanded structural formula
  • Condensed structural formula
  • Skeletal structural formula
  • Line-angle structural formula

Structural formula which shows all the atoms in a molecule along with all the bonds that is connecting the atoms present in the molecule is known as Expanded structural formula.

Structural formula in which grouping of atoms are done and in which the central atoms along with the other atoms are connected to them are treated as group is known as Condensed structural formula.

Structural formula that shows the bonding between carbon atoms alone in the molecule ignoring the hydrogen atoms being shown explicitly is known as Skeletal structural formula.

Structural formula where a line represent carbon‑carbon bond and the carbon atom is considered to be present in each point and the end of lines is known as Line-angle structural formula.
