Chapter 13, Problem 33RQ

Interpretation Introduction

Interpretation:

Among the compound ${\text{H}}_{\text{2}}{\text{NCH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{NH}}_{\text{2}}$ or ${\text{CH}}_3{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{NH}}_{\text{2}}$ with higher boiling point has to be determined.

Concept Introduction:

Temperature at which vapor pressure becomes equal to the external pressure is termed as boiling point temperature. As increase in temperature, weakens the intermolecular forces between the molecules. Therefore, with increase in temperature, boiling point temperature decreases.

The bond formed between hydrogen atoms attached to electronegative atom and other electronegative atoms like fluorine, oxygen, and nitrogen is termed as hydrogen bond.
