Question

What products are formed when each compound is subjected to a Kiliani–Fischer synthesis?

(a.)

(b.)

Short answer

Answer

(a.)

(b.)

Step-by-step solution

Kiliani-Fischer synthesis

In the Kiliani-Fischer reaction, the monosaccharide is synthesized by the addition of new chiral carbon to the open-chain aldehyde. Kiliani-Fischer increases the length of the chain.
