Put the following acids in order in terms of increasing acid strength and explain why. Which of the following is NOT -conjugate acid-base pair a) HI< HBr< HCI<HF. The size of the halide is decreasing and the bond between the holide and the H is strengthening. b) HI< HBr< HCI <HF. The size of the halide is decreasing and the bond between the halide and the H is weakening. e) HF<HCI<HBr<HI. The size of the halide is increasing and the bond between the halide and the H is strengthening. d) HF<HCI<HBr<HI. The size of the halide is increasing and the bond between the halide and the H is weakening.
