Why not duplet Methylene
« on: September 13, 2005, 01:08:00 AM »
Hi ,

 Can  anyone please tell me  why  there is  no   Duplet methylene? There are Singlet( both the electrons are paired ) and Triplet ( Electrons are uppaired ).

On  what  basis  the Methulene Radical  CH2: is named?

Regards
Nitin

Because the 2 electrons can either align their spins with each other or oppose to each other.

If S is the total spin and s(1) and s(2) is the value of the individual spin of electron(1) and electron (2) respectively. Then the total spin S is shown below.

S=s(1) + s(2)
  =1/2 + 1/2 = 1
or
 =1/2 + -1/2 = 0

Multiplicity (M) is defines as below.

M = 2S + 1
Inputing the values of S above.

M = 2(1) + 1 = 3 ie Triplet
M = 2(0) + 1 = 1 ie Singlet
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex
