Iodine consists of simple molecules. Which of the following is a property of simple molecules? A - Have no overall electric charge
B - They conduct electricity
C - Have high boiling points
D - Have giant structures

A - Have no overall electric charge

Explanation:

Ideally, atoms of elements are chemically bonded to form molecules. A molecule is said to be a SIMPLE MOLECULE if it contains only a few atoms linked strongly together by covalent bonding. Examples of simple molecules are O2, CO2, I2, Cl2 etc.

The following properties are possessed by simple molecules:

- They have no overall electric charge

- They have low melting and boiling points due to the weak intermolecular forces that are easily overcomed when temperature is applied.

- Since they have no net charge, they do not conduct electricity.

- As their name implies, they rather have simple structures.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
