`(CH_3)_2CO underset((HCl))overset(NaCN)to A underset(Delta)overset(H_3O^(+))to B` अभिक्रियाओं के उपरोक्त अनुक्रम में A तथा B हैं

Options

A. `(CH_(3))_(2)C(OH)CN, (CH_(3))_(2)CHCOOH`
B. `(CH_(3))_(2)C(OH)CN, (CH_(3))_(2)C(OH)_(2)`
C. `(CH_(3))_(2)C(OH)CN, (CH_(3))_(2)C(OH)COOH`
D. `(CH_(3))_(2)C(OH)CN, (CH_(3))_(2)C=O`

Answer

C

Explanation

(i) `(CH_(3))_(2)CO overset(NaCN)underset(HCl)rarr (CH_(3))_(2)-C(OH)(CN)` (सायनोहाइड्रिन) (A)
(ii) `underset((A))((CH_(3))_(2)-C(OH))(CN) overset(H_(3)O^(+))rarr`
`rarr underset((B))((CH_(3))_(2)C(OH)COOH)`
