Which of the following best justifies why chalk (calcium carbonate) has a higher melting point than motor oil (a large compound containing only carbon and hydrogen.)

• the motor oil has very strong London dispersion forces

• calcium carbonate has ion-ion attractions which are much stronger than the London dispersion forces found in motor oil.

• motor oil has hydrogen bonding but it is not as strong as the ion-ion forces in chalk
