Question

le from highest to lowest acidity. HO SH Hint analyze in thei order 1-ATOM 2- RESONANCE 3- INDUCTIVE EFFECTS 4-ORBITALS There are four different types of atoms 1- H--O (acid) a. b. C. d. Base is stabilized since the negative charge is on an electronegative atom (0) Base is stabilized by resonance (other Oxygen) No inductive Sp3 orbital 2- C-H (close to Carbonyl) The negative charge is on a relatively neutral atom (C) Not favorable b. a. This negative charge can be stabilize by resonance with the Oxygen I carbonyl Slight inductive effect from S-H d. c. Sp3 orbital 3- CH2 close to SH a. The negative charge is on a relatively neutral atom (C) Not favorable b. No stabilization for resonance c. Inductive effect form SH d. Sp3 orbitals 4- H bound to H The negative charge is on an electronegative atom. S accommodating the neyy created negative charge No stabilization by resonance No inductive effects No significant orbital contribution (all the valence electrons are far away from the nucleus: big atoms, 3"d row in the periodic table) a. is alos a large atom, capable of b. c. d. My rank 1>4>2>3

Explanation / Answer

The rank of H atom from high acidity to low acidity

Atom = 1>4>3>2

Resonance =   1>2>3=4

Inductive effect = 3>2>1=4

Orbitals = 1=2=3>4
