Which one of the following correctly ranks the compounds in order of lowest vapor pressure to highest vapor pressure based only in intermolecular forces? A) I₂

What is the predominant intermolecular force in the liquid state of each of these compounds: water (H,O), carbon tetrachloride (CCI4), and difluoromethane (CH,F,)? Drag the appropriate items to their respective bins. Reset Help H20 CH2F2 Dipole-dipole forces Hydrogen bonding Dispersion forces

Which of the following substances has only London Dispersion forces?   A KNO4   B HI   C CCl4   D All of the above

What intermolecular forces are present between two molecules of CH₃CH₂SH? A.)dispersion only B.)dipole-dipole only C.)hydrogen bonding only  D.)dispersion and dipole-dipole E.)dispersion and hydrogen bonding

Compounds with higher vapor pressure boil at temperatures.

What type(s) of intermolecular forces are expected between CH3CH2CHO molecules? -H- H Indicate with a Y (yes) or an N (no) which apply. dipole forces induced dipole (London dispersion) forces hydrogen bonding Y

Order the following by increasing surface tension, according to intermolecular forces trends. Compound 1 has the lowest surface tension, 4 has the highest surface tension. SO3 HF CO2 CH20 > > > >

Which do you predict to have a higher boiling point and why? 1. CH3OH 2. CH3CH₂CH₂OH Because 3. more hydrogen bonding interactions need to be overcome requiring more energy. 4. the London dispersion forces are stronger because the molecule is larger, so more energy is required to overcome them. 5. there are more covalent bonds to break, requiring more energy. 2 and 3 2 and 5 2 and 4 1 and 3 1 and 4

What type(s) of intermolecular forces are expected between PCl3, NH2Cl, and SiH4 molecules? Indicate with a Y (yes) or an N (no) which apply. dipole forces   induced dipole forces   hydrogen bonding

Which of the following statements about PH3, C2H6, and NH3 is false? Your answer: PH3 has the strongest intermolecular forces. O Only dispersion forces exist between C2H6 molecules. O NH3 has a higher normal boiling point than C2H6. O Hydrogen bonding exists only in NH3. Dispersion forces and dipole-dipole interactions exist between PH3 molecules.
