Question

Rank the following compounds in order of lowest to highest melting point.

KCl CH3-O-CH3 CH3-CH2-CH3 CH3-CH2-NH2
Don't worry about subscripts or dashes, enter CH3-CH3 as CH3CH3.

Lowest Melting Point to Highest Melting Point

Answer 1

Classify each of the compounds into types of bonds.

Answer 2

1) Ionic bonds are formed when metallic atoms donate valence electrons to non-metallic atoms. The resulting ions have opposite charges and attract each other into rigid lattices. This bonding structure gives high bond strength that provides brittle substances with high melting points and low conductivity. so KCL has the highest m.p

2) CH3-O-CH3 is a polar molecule (difference in electronegativity electrons are shared unequally) and a require a greater amount of energy to break their bonds compared to non polar molecule.

3) CH3-CH2-CH3 is held by weak dispersion forces.

4) CH3-CH2-NH2 is an example of hydrogen bond, hydrogen is the strongest type of intermolecule.(The hydrogen is attached directly to one of the most electronegative elements, causing the hydrogen to acquire a significant amount of positive charge.
Each of the elements to which the hydrogen is attached is not only significantly negative, but also has at least one "active" lone pair.) F,O,N most electronegative elements.
