Question: Select correct statement(s) out of following?...

Select correct statement(s) out of following?

A

is more reactive than towards reaction with PhMgBr

B

→hvCl2(aq)\xrightarrow[\text{hv}]{\text{Cl}_2\text{(aq)}} (major product)

C

2 →(Catalytic)Conc. H2SO4\xrightarrow[\text{(Catalytic)}]{\text{Conc. H}_2\text{SO}_4} (Major)

D

D-glucose + D-mannose + D-fructose →PhNHNH2\xrightarrow{\text{PhNHNH}_2} only one osazone

Answer

A, B, C, D

Explanation

Solution

All the given statements are correct.

  • Statement A is correct because the carbonyl group in the first compound is more electrophilic due to the electron-withdrawing nature of the adjacent groups.

  • Statement B is correct as chlorination occurs at the benzylic position under photochemical conditions.

  • Statement C is correct as it depicts a dimerization reaction under acidic conditions.

  • Statement D is correct since D-glucose, D-mannose, and D-fructose give the same osazone because they differ only at C-1 and C-2, which are involved in osazone formation.
