Interpretation Introduction

a) C8H?O2, has two rings and one double bond.

Interpretation:

The number of hydrogens present in C8H?O2 which has two rings and one double bond.

Concept introduction:

Each ring or a double bond in a molecule corresponds to a loss of two hydrogens from the formula of alkane. Hence two hydrogens are to be added for each to arrive at the molecular formula of the parent alkane. Further, If the molecular formula of a compound contains halogens, oxygen and/or nitrogen, then the number of halogens is to be subtracted from the number of hydrogens, the number of oxygens to be ignored and number of the nitrogens is to be added to the number of hydrogens, in arriving the number of hydrogens.

To determine:

The number of hydrogens present in C8H?O2 having two rings and one double bond.

Interpretation Introduction

b) C7H?N has two double bonds.

Interpretation:

The number of hydrogens present in C7H?N which has two double bonds.

Concept introduction:

Each ring or a double bond in a molecule corresponds to a loss of two hydrogens from the formula of alkane. Hence two hydrogens are to be added for each to arrive at the molecular formula of the parent alkane. Further, If the molecular formula of a compound contains halogens, oxygen and/or nitrogen, then the number of halogens is to be subtracted from the number of hydrogens, the number of oxygens to be ignored and number of the nitrogens is to be added to the number of hydrogens, in arriving the number of hydrogens.

To determine:

The number of hydrogens present in C7H?N having two double bonds.

Interpretation Introduction

c) C9H?NO, has one ring and three double bonds.

Interpretation:

The number of hydrogens present in C9H?NO which has one ring and three double bonds.

Concept introduction:

Each ring or a double bond in a molecule corresponds to a loss of two hydrogens from the formula of alkane. Hence two hydrogens are to be added for each to arrive at the molecular formula of the parent alkane.

To determine:

The number of hydrogens present in C9H?NO having one ring and three double bonds.
