Question

can you please answer this in line drawing and have it set out clearly, as the previous answer was very unclear

Give the products of the reaction of 1-pentanol, with (a) propanoic acid, with conc. sulfuric acid catalyst; (b) hot conc. sulfuric acid; (c) potassium dichromate in dilute sulfuric acid; NAD+ with an enzyme catalyst 5. Give the products of the reaction of butanal, with: (a) sodium borohydride, in methanol (b) hydrogen cyanide, with catalytic cyanide (c) potassium dichromate in dilute sulfuric acid; (d) methanol, with a trace of acid catalyst; (e) ethylamine (CH3CH2NH2) Give the products of the reaction of cyclohexanone, with reagents 5(a)-e) above.
