Vedclass · Answer

(NONE) Sucrose is a disaccharide composed of $\alpha-D$-glucose and $\beta-D$-fructose. This is a correct match.Bakelite is a polymer formed by the condensation of formaldehyde and phenol. This is a correct match.Lactose is a disaccharide formed by $\beta-D$-galactose and $\beta-D$-glucose. The option $C$ states $\beta-D$-glucose and $\beta-D$-galactose,which is technically correct in terms of components,but the standard representation for lactose is $\beta-D$-galactose linked to $\beta-D$-glucose. However,looking at the options,all are chemically correct. Re-evaluating: Sucrose is $\alpha-D$-glucose + $\beta-D$-fructose (Correct). Bakelite is phenol + formaldehyde (Correct). Lactose is $\beta-D$-galactose + $\beta-D$-glucose (Correct). $PHBV$ is $3$-hydroxybutanoic acid + $3$-hydroxypentanoic acid (Correct). Given the context of typical textbook questions,if this is a multiple choice question where one must be incorrect,there might be a typo in the question or options. Assuming the question asks for the incorrect match,and all are correct,the question is flawed. However,based on standard curriculum,all these statements are factually correct.
