Structural formula for the given aldehyde has to be drawn. Concept Introduction: Structure of the given aldehyde 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 these information, the structure for the given compound can be drawn. In an aldehyde 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.

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

Interpretation Introduction

Interpretation:

Structural formula for the given aldehyde has to be drawn.

Concept Introduction:

Structure of the given aldehyde 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 these information, the structure for the given compound can be drawn. In an aldehyde 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.

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.

Conclusion

Structural formula for the given aldehyde is drawn.

Answer 30

(d)

Interpretation Introduction

Interpretation:

Structural formula for the given aldehyde has to be drawn.

Concept Introduction:

Structure of the given aldehyde 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 these information, the structure for the given compound can be drawn. In an aldehyde 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.
