JEE Mains · Chemistry · STD 12 - 7. Alcohol, phenol and ethers
Given below are two statements: One is labelled as Assertion \(A\) and the other is labelled as Reason \(R\). Assertion \(A:\) Butan\(-1-\)ol has higher boiling point than ethoxyethane. Reason \(R:\) Extensive hydrogen bonding leads to stronger association of molecules. In the light of the above statements, choose the correct answer from the options given below:
- A Both \(A\) and \(R\) are true and \(R\) is the correct explanation of \(A\)
- B \(A\) is true but \(R\) is false
- C Both \(A\) and \(R\) are true but \(R\) is not the correct explanation of \(A\)
- D \(A\) is false but \(R\) is true
Answer & Solution
Correct Answer
(A) Both \(A\) and \(R\) are true and \(R\) is the correct explanation of \(A\)
Step-by-step Solution
Detailed explanation
Butan\(-1-\)ol \(\left( CH _3 CH _2 CH _2 CH _2 OH \right)\) can undergo hydrogen bonding. Ethoxyethane \(\left( CH _3 CH _2-\right.\) \(O - CH _2 CH _3\) ) has no hydrogen (attached with \(F\), \(O , N\) ) which can undergo hydrogen bonding. More is the extent of intermolecular…
