PF3(CH3)2 Structure: Molecule & Properties

  • Thread starter Juwad
  • Start date
In summary, there was a discussion about the molecular structure of PF3(CH3)2 and whether it can have 5 bonds. Steve was unsure about the ratio of 3:5 bonds for P and mentioned that there may be other factors, such as hybridization of orbitals, at play. Steve also suggested a possible structure with P in the middle, 3 Fs attached with single bonds, and two methyl groups also attached to P. However, Steve admitted that he hasn't taken a chemistry course in over 3 decades and hopes that someone more knowledgeable can provide further clarification. Overall, the conversation ended with Steve wishing the person luck in their inquiry."

P, at times, can have 5 bonds.

Hope that helps.

Not sure the ratio of 3:5 bonds for P. Cannot comment on your compound. There are many, many more intelligent people at this site than I. Hybridization of orbitals might come into play here. Perhaps someone can correct/add to what has been said so far?

I have a possible structure with the P in the middle, 3 Fs with single bonds to the P and two methyl groups, also attached to the P. If I am wrong or misleading you - don't mean to do so. Just that I haven't taken a chemistry course in over 3 decades!

Best of luck.
