निम्न अभिक्रिया के लिये सही मध्यवर्ती एवं उत्पाद है
`H_3 C-C ≡CH underset(H_2 SO_4) overset(H_2 O H_2 SO_4) to underset((A))("मध्यवर्ती " to underset(B)("उत्पाद ")`

Options

A. `A=H_(3)C-underset(SO_(4))underset(|)(C)=CH_(2),B=H_(3)C-underset(O)underset(||)(C)-CH_(3)`
B. `A=H_(3)C-underset(OH)underset(|)(C)=CH_(2),B=H_(3)C-underset(SO_(4))underset(||)(C)-CH_(3)`
C. `A=H_(3)C-underset(O)underset(||)(C)-CH_(3),B=H_(3)C-C-=OH`
D. `A=H_(3)C-underset(OH)underset(|)(C)=CH_(2),B=H_(3)C-underset(O)underset(||)(C)-CH_(3)`

Answer

D

Explanation

`CH_(3)-C-=CHunderset(HgSO_(4))overset(H_(2)O,H_(2)SO_(4))rarrCH_(3)-overset(OH)overset(|)(C)=CH_(2)`
मध्यवर्ती (इनॉल रूप) `(A)overset("वलावयवता")iffunderset(("कीटो रूप"))underset(("ऐसीटोन")(B))(CH_(3)-overset(O)overset(||)(C)-CH_(3))`
अतः `A=CH_(3)-underset("प्रोपीन-2-ऑल")underset(OH)underset(|)(C)=CH_(2)B=CH_(3)-underset(("प्रोपेनॉन"))underset(O)underset(||)(C)-CH_(3)`
