Q. 

Which reagent can best distinguishes 3-pentanol and 3-methyl-3-pentanol?

An organic compound X (C₅H₁₂O) gives effervescence with NaH. X on treatment with acidic CrO₃ solution turns solution to blue-green forming C₅H₁₀O₂. Also X can be resolved into enantiomers. The correct statement regarding X is

An organic compound C₄H₁₀O (X) on reaction with I₂/red-P give s C₄H₉I which on further reaction with AgNO₂ gives C₄H₉NO₂ (Y). Y on treatment with HNO₂ forms a blue solution which turns to red on making solution slightly alkaline. The possible identity of X is

An organic compound X (C₇H₁₆O) on treatm ent with concentrated HCI solution forms immediate turbidity even in the absence of ZnCl₂. Also, X is resolvable into enantiomers. The correct statement concerning X is

Which reagent given below does not produce any visible change when added to ethylene glycol?

Which of the following is least likely to form turbidity with HCI in the presence of ZnCI₂ at room temperature?

The correct statement regarding 3-ethyl-3-hexanol is

An alcohol has molecular formula C₆H₁₂O X and it gives immediate turbidity with cold, concentrated HCI even in the absence of ZnCI₂. X can also be obtained by treatment of an ether with excess of CH₃MgBr followed by acid hydrolysis. Hence, the correct statement regarding X is
