Concepts and reason
This problem is based on the concept of Nuclear magnetic resonance which involves the absorption of radiations in the radio frequency region. This spectroscopy is generally used for the determination of the type and number of protons present in a molecule.
Fundamentals
A spinning charge creates a magnetic field and therefore behaves as a tiny magnet . The spinning nuclei generate a magnetic field on exposure to an external magnetic field . If an external magnetic field is applied , spinning nuclei can get oriented in two ways:
The magnetic field due to nuclei is in the same direction as the external field. In this case, the nuclei are said to be in a low energy spin state.
The magnetic field due to nuclei is in the opposite direction as the external magnetic field. In this case, the nuclei are said to be in high -energy spin state.

The moles of oxygen required to completely react with 1-mole acetylene is 2.5 mol.
The moles of reactant and product in a chemical reaction to the whole number ratio is given by the stoichiometric coefficient of the balanced chemical equation.
<h3>Computation for the moles of oxygen</h3>The balanced chemical equation for the reaction is :
From the balanced chemical equation, the 2 moles of acetylene react with 5 moles of oxygen.
The moles of oxygen react with 1 mole of acetylene are:
The moles of oxygen required to completely react with 1-mole acetylene is 2.5 mol.
