ARIO Review: Ex.tom H VS. more audic CHbond Utbond CV.OENU=more EN more audil deproinated: y more stalde more stalde stronger CB Aud ARIO helps us decade what compond is more stable /more dudic EX.A O-H ۷۰ S-H find which is more stable→ more qudlu starting comp. CB: V. S = Size: down a group size increases stabiuty Increasts s is larger than o - more acidic / better able to stabalize charge Resonance: Noreson. think is there any resonance stabalization for this charge. Having resonance makes makes an anion/allyllic pi pond and EN IT to lone pair = resonance molecule more stable. stabalized When its more stable as a CB = stronger Acid. Ex. induction The dipole offers a uttle more Stability more audity these chilonne make the molecule have a dipole moment pulling electron density toward chionne 7.Sarne atom: both have resonance: R so must look at another differentia-ting factor This is useful when there are no EN elements and is good when comparing hydrocanoons Alkyne more Audic A: all attached to ac doesn't help R: None have resonance doesni help I: NO EN elements/dipules doesn't help o the only compantive factor A: Sp (3 bunds + ILP = 4 Sp³): 25%. S 3 B: Sp² (2 bonds + ILP = 3 Sp²): 33% S c: sp (I bond + ILP = 2 sp): 50%. S *As you gain more s character to the oniltal the ability to stabalize negative charge increases Sonitals are closer to the nucleus more → stable more quidic
