Carboxylic acid is reacted with thionyl chloride \( \left(\mathrm{SOCl}_{2}\right) \) to form an organic compound A. Compound A was treated with Lithium aluminum tri(tert-butoxy)hydride to form Compound B. The functional group present in compound B will be: tertiary alcohol secondary alcohol primary alcohol aldehyde Question 6 5 pts When a butan-2-ol is treated with \( \mathrm{Na}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7} / \mathrm{H}_{2} \mathrm{SO}_{4} \), the product obtained will be: di-n-butylether butanoic acid methyl ethyl ketone butan-2-al Choose the reaction which will lead to the formation of a methyl ester: \[ \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{COOH}+\mathrm{CH}_{2} \mathrm{~N}_{2} \] \[ \mathrm{CH}_{3} \mathrm{COCl}+\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{OH} \] \[ \mathrm{CH}_{3} \mathrm{COOH}+\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{OH} \] \[ \mathrm{CH}_{3} \mathrm{COOH}+\mathrm{H}_{2} \mathrm{SO}_{4} \] Question 8 5 pts In the Wittig reaction, n-butyl lithium (BuLi, \( \mathrm{CH}_{3}\left(\mathrm{CH}_{2}\right)_{2} \mathrm{CH}_{2} \mathrm{Li} \) ) acts as a : ylide electrophile nucleophile base
