Question

Are questions 6-10 correct? The angles between sp^2 hybrid orbitals are 109.5 degree. True False Nonpolar compounds are soluble in nonpolar solvents and insoluble in polar solvents. True False To make a sp^3 hybrid orbital, one s atomic orbital is hybridized with p atomic orbitals. True False The number of lone pairs of electrons on the central atoms is an import factor used to determine the molecular shape or molecular geometry. True False Octane, C_8H_18, boils at 125 degree C as compared to water, which boils at 100 degree C. This information suggests that the dispersion forces in nonpolar octane molecules are stronger than dispersion forces and hydrogen bonding in water. True False

Explanation / Answer

Your answers from 1 to 9 was correct. But last 10 th question answere is (false ) . Because dispersion forces in non polar molecules is lesser than the dispersion forces in polar molecules . high boiling point of octane due to large molecule than water ( smaller) . Larger the molecule larger the dispersion force.
