Neco Model Questions Vol1 2024 Chemistry Question 43
Practice objective / multiple choice question 43 from the 2024 Neco Model Questions Vol1 Chemistry examination.
When 10.0 g of 2‑bromo‑2‑methylpropane (M = 137.0 g·mol^{-1}) is treated with excess aqueous NaOH, two competing reactions occur: (i) substitution giving tert‑butyl alcohol (C_4H_{10}O), and (ii) elimination giving isobutene (C_4H_8). Experimental data show that 80 % of the substrate follows the substitution pathway and 20 % follows elimination. (a) Calculate the mass of tert‑butyl alcohol obtained. (b) Express the percentage yield based on the theoretical maximum if the whole substrate had undergone substitution.
