What is the relative formula mass of c2h5co2h

74

Explanation:

The compound is properly written as: C₂H₅CO₂H

To find the relative formula mass, we must know the atomic mass of the the atoms making up the compound first. The atomic mass is given by the periodic table:

                           C = 12g

                            H = 1g

                            O = 16g

Now use the number of each atom present in the compound to multiply the atomic mass and add up:

C₂H₅CO₂H = (2x12) + (5x1) + (1x12) + (2x16) + (1x1) = 24+5+12+32+1 = 74

It has no unit

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
