Explain the overall trend in the following melting points in terms of the forces among particles in the solids indicated.

msp;  Hydrogen ,  H 2                                                                         259  ° C

msp;  Ethyl alcohol ,  C 2 H 5 OH                                         114  ° C

msp;  Water ,  H 2 O                                                                                         0   ° C

msp;  Sucrose ,  C 12 H 22 O 11                                                             186  ° C

msp;  Calcium chloride ,  CaCl 2                                     772  ° C

Interpretation Introduction

Interpretation:

The overall trend in the given melting points in terms of the forces among particles of the indicated solids must be explained.

Concept Introduction:

Stronger the forces among particles higher are the melting point of the substances.

Explanation

Hydrogen has weaker van der Waal forces. Ethyl alcohol has hydrogen bonding forces which is stronger than hydrogen. Water has extensive hydrogen bonding and thus it has stronger intermolecular attraction as compared to ethyl alcohol...
