GASES, LIQUIDS AND SCLID Understending conceptuat components of the enthalpy of solution A small amount of acetonitrile (CH, CN) is dissolved in a large amount of water. Imagine separating this process into the four stages sketched below. (These sketches show only a portion of the substances, so you can see the density and distribution of atoms and molecules in them.) CH,CN H2O solution Use these sketches to answer the questions in the table below is negative The enthalpy of solution&H; soln whern CH3CN dissolves in water. Use this information to list the stages in order of increasing enthalpy Would heat be absorbed or released if the system moved from Stage C to D? o absorbed o released e neitner aosorpea nor none a ionic bonding force a covalent bonding force moving from Stage C to D? Check all that apply hydrogen-bonding force G dipole force a ion-dipole force a dispersion forceExplanation / Answer
1:
As Delta H is negative it means that it is an exothermic reaction which means heat will be released into the surroundings
2.:
Ionic Bonding Force: Force acting for binding ions with water / solvent molecules. as there is no ion present so ionic bonding force will not be present.
Covalent Bonding force: Present within a covalent molecule for binding atoms. so not present here
Metal Binding Force: Forces acting as binding of a metal ion in a complex or in a solution. SO not present here.
H- Bonding force: Forces acting to form H bonding. Here possibilities of H bonding is there as electronegative N atom is present. So this force will act
Dipole Force: Act in the formation of the dipole. Here CH3CN is a polar molecule, as Electronegative N is present. also, H2O is a polar molecule. so dipole force will act here
Ion-Dipole: No ion present here so not present
Dispersion force: act for nonpolar molecules. not present.
