Practice objective / multiple choice question 36 from the 2020 Gce Model Questions Vol1 Chemistry examination.
A compound A (C6H5CH2Cl) undergoes nucleophilic substitution with NaOH to give benzyl alcohol with an (80\%\) yield. The alcohol is then oxidised with PCC to give benzaldehyde with a (70\%\) yield. However, (10\%\) of the benzyl alcohol formed is converted to toluene as a side reaction. Assuming the side reaction occurs after the first step, calculate the overall percentage of the original A that ends up as benzaldehyde.
