323047 Which among the following isomers of \(\mathrm{C}_{4} \mathrm{H}_{9} \mathrm{OH}\) has lowest boiling point?

1 Iso- Butyl alcohol
2 n-Butyl alcohol
3 tert-Butyl alcohol
4 sec-Butyl alcohol
CHXII11:ALCOHOLS, PHENOLS AND ETHERS

323048 Assertion :
Alcohols have higher boiling points than ethers of comparable molecular masses.
Reason :
Alcohols and ethers are isomeric in nature

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
CHXII11:ALCOHOLS, PHENOLS AND ETHERS

323049 Assertion :
\(\mathrm{CH}_{3} \mathrm{OCH}_{3}\) and \(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}\) has comparable molecular weight but boiling point of \(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}\) is more than dimethyl ether.
Reason :
\(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}\) forms intermolecular \(\mathrm{H}\) -
bonding while \(\mathrm{CH}_{3} \mathrm{OCH}_{3}\) forms intramolecular \(\mathrm{H}\)-bonding.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.

323050 Which among the following compounds has highest melting point?

1 Phenol
2 \(\mathrm{p}\) - Nitrophenol
3 \(\mathrm{p}\) - Cresol
4 o-Nitrophenol
CHXII11:ALCOHOLS, PHENOLS AND ETHERS

323051 An ether is more volatile than an alcohol having the same molecular formula. This is due to

1 dipolar character of ethers
2 alcohols having resonance structures
3 intermolecular hydrogen bonding in ethers
4 intermolecular hydrogen bonding in alcohols.
