Chapter 23, Problem 1ASA

Please answer the questions in the photos and please revise any wrong answers. Thank you

(Please be sure that 7 carbons are available in the structure )Based on the 1H NMR, 13C NMR, DEPT 135 NMR and DEPT 90 NMR, provide a reasoning step and arrive at the final structure of an unknown organic compound containing 7 carbons. Dept 135 shows peak to be positive at 128.62 and 13.63 Dept 135 shows peak to be negative at 130.28, 64.32, 30.62 and 19.10.

-lease help me answer the questions in the photo.

Define electronegativity.

Why do only the immediately adjacent H's show up in the number of peaks?  Are there normally peaks for the H's that are 2-3 carbons away?

Please help me understand this question. Thank you. Organic Chem 1

For the reaction below, the concentrations at equilibrium are [SO₂] = 0.50 M, [0] = 0.45 M, and [SO3] = 1.7 M. What is the value of the equilibrium constant, K? 2SO2(g) + O2(g) 2SO3(g) Report your answer using two significant figures. Provide your answer below:

I need help with this question. Step by step solution, please!

Zn(OH)2(s) Zn(OH)+ Ksp = 3 X 10-16 B₁ = 1 x 104 Zn(OH)2(aq) B₂ = 2 x 1010 Zn(OH)3 ẞ3-8 x 1013 Zn(OH) B4-3 x 1015
