Scientific Owl on Instagram: "NaBH₄ (sodium borohydride) is a mild reducing agent that donates hydrogen to reactive carbonyl groups. It easily reduces aldehydes to primary alcohols and ketones to secondary alcohols, but it cannot reduce esters, amides, or carboxylic acids because these groups are more stable and need stronger reducing agents like LiAlH4(Lithium aluminum hydride). . . . #organicchemistry #chemistry #chemistrymeme #kotastudentslife #iit"
