Explanation:
This is because gas particles are free to move as they are not held in place by strong molecular forces while particles in a solid are
In order to find out the ranking of ions basicity, check the
pKa values of each ions. The principle that you need to remember is that the
stronger the acid the weaker the corresponding conjugate base. The pKa dictates
acid value of the compound. The answer would be CH3NH, CH3O-, and CH3CH2-.
Answer:

Explanation:
