Question 15

what is an isomer

Answer 15

compounds with the same molecular formula but different structural formula

Question 16

the solubility, boiling point and volatility (ease of evaporation) of a compound can be predicted by considering: (4)

Answer 16

•the presence of O-H or N-H bonds, which implies hydrogen bonding
•the spatial arrangement of polar covalent bonds which could result in a molecule possessing a permanent dipole
•molecular size which would affect LDFs
•the polarities of solute and solvent. polar or ionic compounds tend to be soluble in polar solvents, non polar compounds tend to be soluble in non polar solvents

Question 17

solubility, boiling point and volatility can be explained in terms of the type and strength of what

Answer 17

the intermolecular forces present
