(a)
Interpretation:
The type of intermolecular force exhibited by ethanol and dimethyl ether needs to be determined.
Concept Introduction:
The intermolecular force is defined as the force which occurs between the one molecule to another as attraction. The intermolecular force is of following types −
- Hydrogen bond this type of intermolecular force exists in that molecule in which the hydrogen atom is covalently bonded with the atom with high electronegativity and it has strong intermolecular attraction.
- Dipole-Dipole interaction is a type of intermolecular force occurs only in the polar molecules and increase with the polarity of the molecule.
- London Dispersion intermolecular force occurs in the polar or non-polar molecule or atoms.
(b)
Interpretation:
The compound with higher boiling point between ethanol and dimethyl ether needs to be determined.

- The fire releases 2.80 x 107 Joules of heat energy for each liter of oil burned. The water starts out at 24.5 °C, raising the water's temperature up to 100 °C, and then raises the temperature of the resulting steam up to 325 °C. How many liters of water will be needed to absorb the heat from the fire in this way, for each 1.0 liter of crude oil burned? 4186 J/(kg°C) = heat of water 2020 J/(kg°C) = heat of steam 2,256,000 (i.e. 2.256 x 106) J/kg = latent heat of vaporization for water (at the boiling point of 100 °C).arrow_forward6 Which of the following are likely to be significant resonance structures of a resonance hybrid?
