How is this different from ionic bonds?

Open Ended

Give an example of covalent compound (aside from CO₂ and H₂O)

Multiple Choice

Water is an example of a covalent compound. If it is not capable of conducting electricity, then why are prone to electrocution when you throw an electric dryer in a bath tub?

• Because the blower has electricity

• Because the water in the bath tub is not pure water

• Because our body i a conductor of electricity

• Because of the strong voltage of the hair dryer

Multiple Choice

Sugar and oil are both examples of covalent compounds. Sugar dissolves in water while oil doesn't. Why is this so?

• Sugar is polar covalent while oil is nonpolar covalent. Sugar being polar can be dissolved in water (which is polar too).

• Sugar is soluble in water because the molecules are smaller as compared to oil.

• Sugar is non-polar covalent while oil is polar covalent. Like dissolves like so water (being nonpolar) will dissolve sugar.

• Sugar will dissolve in water because the particles will dissociate easily as compared to oil which is immiscible with water.
