Ester to amide 2. Acid anhydride to acid halide 3. Acid anhydride to ester 4. Amide to esterarrow_forwardWrite TRUE if the underlined word/phrase makes the statement correct. Otherwise, write the correct WORD/PHRASE that will make the statement true. 1. Aldehydes and ketones generally react in a mechanism known as nucleophilic substitution reaction at the carboxylic oxygen. 2. 1-cyclopentylethan-1-one will test positive in baeyer's test and will test positive in tollen's test. 3.
