Chemistry- U4 AOS1

Question 1

intermolecular bonds

Answer 1

forces of attraction or repulsion which are present between neighboring molecules and causing them to be linked
Ex. *hydrogen, dipole-dipole, dispersion *

Question 2

Polar

Answer 2

those which have a net dipole moment due to the differences in the electronegativities of the atoms present in the molecule which do not allow to cancel the dipoles
Ex. H2O

Question 3

Non-polar

Answer 3

those which have net dipole moment as zero as the dipoles of the atoms are cancelled out within the molecule.
Ex. H2, CO2, carbon tetrachloride

Question 4

intramolecular

Answer 4

forces that hold atoms together within a molecule
Ex. Hydrogen, colvalent, ionic

Question 5

Functional group vs homologous series

Answer 5

Functional groups are atoms or groups of atoms in a compound that determine its characteristic reactions

Homologous series is a family of organic molecules with the same functional group, similar chemical properties and different numbers of carbon atoms.
