What are `ul(A), ul(B),ul(C)` in the following reactions ?
(I) `(CH_(3)CO)_(2)Caoverset(Delta)ul(A)`
`II. CH_(3)CO_(2)H overset(HI)underset(Red P)toul(b)`
(III) `2CH_(3)CO_(2)H overset(P_(4)O_(10))toul(C)`

Answer

C

Explanation

(i) `(CH_(3)COO)_(2)Ca overset(Delta)to CH_(3)COCH_(3) +CaCO_(3)`
(ii) `CH_(3)COOH underset("red P")overset(6HI)to CH_(3)-CH_(3)+ 3I_(2)+ 2H_(2)O`
(iii) `2CH_(3)COOH underset(P_(4)O_(10))overset(Delta)to (CH_(3)CO)_(2)O+ H_(2)O`
