Why are ions usually formed during the interaction of metal with nonmetal and not between two metals? ​
Alik [6]

Explanation:

Ions are always formed when metals and non-metals interact because metals are electropositive. They willing release electrons to non-metals that are electronegative.

This activity results in charge separation. The transfer of electrons from one specie to another is what results in an ionic bond and the precedence of charged particles.

Between non-metals, the electrons are jointly shared. Therefore, there is no charge separation.

What is the molecular formula of a hydrocarbon with m+ = 78?
fiasKO [112]

A molecular formula represents the exact number of atoms present for each element in the compound.  

For carbon atom: \frac{78}{12} = 6\frac{6}{12} ( as molar mass of carbon is 12 g/mol)

Now, 6 carbon atoms are present and rest are hydrogen atoms i.e. 6

Thus, formula becomes C_{6}H_{6} ( C_{x}H_{y})

Now, check for unsaturation:

Degree of unsaturation  = \frac{2x+2-y}{2}

Substitute the value of x and y,

Degree of unsaturation  = \frac{2(6)+2-6}{2}

= \frac{12-4}{2}

= 4 implies one ring and three double bonds.

Thus, formula comes out to be C_{6}H_{6} i.e. benzene ring.
