(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)
Consider the following two reactions A and B: 
The numerical value of [molar mass of $x$ + molar mass of $y$] is ___.

Consider the following reaction sequence: 
Given: Compound (x) has percentage composition \(76.6%\ \text{C}\), \(6.38%\ \text{H}\) and vapour density \(=47\). Compound (y) develops a characteristic colour with neutral \(\mathrm{FeCl_3}\) solution. Identify the {INCORRECT statement.}
