Answer:
Bohr's model of the hydrogen atom is based on three postulates:
1) An electron moves around the nucleus in a circular orbit,
2) An electron's angular momentum in the orbit is quantised,
3) The change in an electron's energy as it makes a quantum jump from one orbit to another is always accompanied by the emission or absorption of a photon. Bohr's model is semi-classical because it combines the classical concept of electron orbit (postulate 1) with the new concept of quantisation ( postulates 2 and ).
Indeed it is. Reasons being that the hydrogen bonds in the 1-propanol is difficult to break. Hence, more energy or heat is needed to be applied. Ethyl methyl ether on the other hand doesn't have hydrogen bonds and that explains why it has a lower boiling point.
