Strutural isomers `C_2H_5OH` and `CH_3OCH_3` have the same value of

A

Boiling points

B

Vapour pressure at the same temperature

C

Heat of vaporization

D

Gaseous densities at the same temperature and pressure

Text Solution

Verified by Experts

The correct Answer is:
D
Gaseous densities of ethanol anddimethyl ether would be same at same temperature and pressure. The heat of vaporisation, V.P. and b.pts will differ due to H-bondingin ethanol.

C_2H_5OH and CH_3OCH_3 are

The heat of formation of C_(2)H_(5)OH(l) is -66Kcal//mol . The heat of combustion of CH_(3)OCH_(3)(g) is -348Kcal//mol , DeltaH_(f) for H_(2)O and CO_(2) are -68Kcal//mol and -94Kcal//mol . Respectively. Then, the DeltaH for the isomerisation reaction C_(2)H_(5)OH(l)rarrCH_(3)OCH_(3)(g) , and DeltaE for the same are at T=25^(@)C

The heat of formation of C_(2)H_(5)OH(l) is -66 kcal//"mole" . The heat of combustion of CH_(3)OCH_(3) (g) is -348 kcal/mole. DeltaH_(f) for H_(2)O and CO_(2) are -68 kcal/mole respectively. Then, the Delta H for the isomerisation reaction C_(2)H_(5)OH(l)rarrCH_(3)OCH_(3)(g) ,and Delta E for the same are at T=25^(@)C

Which of the following parameteres would be expected to have the same values for C_(2)H_(5)OH and CH_(3)OCH_(3) ?

CH_(3)OCH_(3) is a gas at room temperature while its isomer CH_(3)CH_(2)OH is a liquid of boiling point 78^(@)C this is due to the fact that
