Question

Use modern concept to determine the valency of each individual elements in molecule CH3OH

Answer 1

Answer:

in modern concept for getting electronic configuration of atom we use hunds or Pauli's rule

according to the four block s,p d f

1.the valency of s block element is 2

2.d=10

3.p=6

4.f=14

C belong to p block hence it's electronic configuration will be 1s2,2s2,2p2
