Which of the following pairs are more likely to form a solution? Lewis structures might help.
(1) methanol and hexane
(2) water and octane
(3) water and octyl alcohol
(4) acetone and octane
(5) chloroform and acetone
Homework Answers
like dissolves like. means polar , polar make solution
non polar , non polar make solution
(1) methanol and hexane
methanol is polar and hexane is non polar. so can not form solution
(2) water and octane
water is polar and octane is non polar , so they can not make solution
(3) water and octyl alcohol
water is polar and octyl alcohol is non polar (it has long chain) , so they can not make solution
(4) acetone and octane
acetone is polar and octane is non polar, so they can not make solution
(5) chloroform and acetone
both are polar , so they make solution

Writing Lewis Structures d. Because oxygen is more electronegative than nitrogen, it is more likely to have a negative formal charge. Which structure would then be the best description of N,O? e. Are the structures that have the N-O-N bond skeleton resonance forms of the structures with the N-N-O skeleton? Explain. 4. Hydrogen isocyanide, HNC, will convert to hydrogen cyanide, HCN, over time. Use their Lewis structures to explain this.
