Question

9-Water (H,0) and the alcohol methanol (CH,OH) are infinitely soluble in each other. The primary intermolecular force responsible for this is Hydrogen bond Which one of the following substances is more likely to dissolve in benzene (C,H)? A) CH,CH,OH B) NH, C) NaCI D) СС, E) HBr 10-Which of the following substances is more likely to dissolve in CH,OH? A) CCI, B) Kr c) N2 D) CH,CH,OH E)H, 11) Which one of the following substances would be the most soluble in CCl,? A) CH,CH,OH B) H,O C) NH, D) C10H22 E) NaCI

Answer 1

Answer 9: Water and methanol are infinitely soluble in water due to intermolecular hydrogen bonding.

Benzene(C₆H₆) is a non polar solvent. Among the substances given, ethanol(C₂H₅OH) , ammonia(NH₃),sodium chloride(NaCl) and hydrogen bromide (HBr).are polar but CCl₄ is a non polar solvent and so is readily soluble in benzene.

E) NaCl being nonpolar is insoluble in benzene as it is a polar molecule.
