(i) The oxidation of the hydroboration product with hydrogen peroxide (H2O2) and hydroxide (OH−) leads to the formation of a diol. The main product will be (CH3–CH2–CH2–CH2OH), 1-propanol.
(ii) Phenol (C6H5OH) reacts with aqueous NaOH to form phenoxide ion (C6H5O−). When phenol reacts with CO2 in the presence of H+, it undergoes carboxylation to form salicylic acid (2-hydroxybenzoic acid).
Main product: Salicylic acid (C6H4(OH)COOH)
For the thermal decomposition of \( N_2O_5(g) \) at constant volume, the following table can be formed, for the reaction mentioned below: \[ 2 N_2O_5(g) \rightarrow 2 N_2O_4(g) + O_2(g) \] Given: Rate constant for the reaction is \( 4.606 \times 10^{-2} \text{ s}^{-1} \).

A coil of 60 turns and area \( 1.5 \times 10^{-3} \, \text{m}^2 \) carrying a current of 2 A lies in a vertical plane. It experiences a torque of 0.12 Nm when placed in a uniform horizontal magnetic field. The torque acting on the coil changes to 0.05 Nm after the coil is rotated about its diameter by 90°. Find the magnitude of the magnetic field.
