Determine the polarity of HCN

• Polar

• Nonpolar

• nonpolar

• polar

Which of the following statements describes a polar molecule?

• because electrons are transferred between atoms, the molecule conducts electricity

• electrons are equally shared between atoms, giving them a negative charge

• the molecule has unequal sharing of electrons, atoms have slightly positive or negative charge

• a polar molecule is perfectly symmetrical, electrons travel freely around atoms

To which term of reference does the following description refer to?

"an unequal distribution of an electrical charge"

• Polar

• Nonpolar

• Both

Answer explanation

The unequal distribution "or sharing" of electrons results in - one side of a Polar Covalent Bond being partially negative while the other side is partially positive.
