Write two different resonance forms for triphenylmethyl cation. Write the structure showing the positive charge at an ortho position.

Triphenylmethane cation is represented by many resonance structures.

Explanation:

The structure number 2 and structure number 4 in the series of resonance structures shown in the image are resonance structures in which the positive charge is at the ortho position.

Resonance structures are also called canonical structures. They help us to picture the actual structure of a molecule.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
