Question

Which pair from the following will not form an ideal solution.

• A.
• B. $\mathrm { H } _ { 2 } \mathrm { O } + \mathrm { C } _ { 4 } \mathrm { H } _ { 9 } \mathrm { OH }$
• C. $\mathrm { C } _ { 2 } \mathrm { H } _ { 5 } \mathrm { Br } + \mathrm { C } _ { 2 } \mathrm { H } _ { 5 } \mathrm { I }$
• D.

Answer 1

Answer: (B)

$\mathrm { H } _ { 2 } \mathrm { O } + \mathrm { C } _ { 4 } \mathrm { H } _ { 9 } \mathrm { OH }$

Answer 2

$\mathrm { C } _ { 4 } \mathrm { H } _ { 9 } \mathrm { OH }$ do not form ideal solution because there is hydrogen bonding between $\mathrm { C } _ { 4 } \mathrm { H } _ { 9 } \mathrm { OH }$.
