D + – glucose is dextrorotatory in nature
WebApr 11, 2024 · The lower melting form is dextrorotatory ([α] 16°), the higher melting one is levorotatory ([α] -6°). The rotation of an aqueous solution of either form, however, gradually changes until a final value of [α] 9.6° is observed. WebAssertion (A): D(+) – Glucose is dextrorotatory in nature. Reason (R): ‘D’ represents its dextrorotatory nature. Answer: The answer is the option (iii) The correct reason is that the nature of glucose is dextrorotatory due to the presence of -OH group og asymmetric carbon attached towards the right side.
