Question

1. complete the properties associated with a covalent bond.

a. melting point is ____________ (high or low)
b. solubility in h₂o ____________ (yes or no)
c. electrical conductivity in aqueous solutions ________ (yes or no)

1. covalent bonds create a (crystal lattice/ true molecules/ sea of electrons) structure.

Explanation:

Covalent - bonded substances have relatively weak intermolecular forces, resulting in low melting points. Their solubility in water depends on polarity; non - polar covalent compounds are insoluble while polar ones can be soluble. They generally do not dissociate into ions in aqueous solutions, so they have low electrical conductivity. Covalent bonds form true molecules as atoms share electrons to achieve a stable electron configuration.

Answer:

a. low
b. it depends (polar covalent compounds can be soluble, non - polar ones are not)
c. no

1. true molecules
