Give the structures of the major products you would obtain from reaction
of phenol with the following reagents:
(a) Br2 (1 mol) (b) Br2 (3 mol)
(c) NaOH, then CH3I (d) Na2Cr2O7, H3O+
The standard potential of the following cell:
Cd (s) / Cd (NO3)2 (aq) // KBr (aq) / AgBr (s) / Ag (s)
Was found to be 0.4731 V at 25°C. The temperature coefficient of the emf of the cell is 1.74 x 10-4 VK-1. Write the cell reaction and calculate ΔG°, ΔS° and ΔH°. [3 marks]
The reaction 2 NO(g) reversible N2 (g)+O2(g) has a KC value of 2400 at 2000 K. If 0.850 M each of N2 and O2 are initially present in a 3.00-L vessel, calculate the equilibrium concentration of NO, N2 and O2.

Isopropyl bromide was treated separately with sodium tert-butoxide and sodium ethoxide under two different condition. Reaction I : at 400C gave almost exclusively compound A, C3H6 Reaction II : at 300C gave compound A along with small amount of ether B, C5H12O. compound A was readily oxidized by a neutral solution of cold dilute potassium permanganate to give a brown precipitate. 5. Which type of reaction is used to explain the formation of A? 6. Draw the structure of the activated complex formed in reaction II that leads to compound A? 7. What happened when product A is treated with cold and alkaline KMnO4 . 8. Write the IUPAC name of compound B 9. Write the equation used to prepare isopropyl bromide
