Complete the following :

Explanation

a. (B) is `1^(@)` alcohol, with 3C, and G.R. contains 2C-, so (I) is `(CH_(2) = O)` (methanal).
b. (B) is `1^(@)` alcohol with 3C, and GR. Contains 1C, so (II) is (ethylene oxide).
c. (D) is `3^(@)` alcohol with 6C, and GR. contains IC, so (III) is ketone with 5C.
So (III) is `overset ((Me--CH_(2)--CH_(2)--CO--Me)) underset (5 4 3 2 1)` (prntan-2-one) or `MeCH_(2)CH_(2)COMe`.
d. (F) is `1^(@)` alcohol with 1C more than GR. (E), so (IV) is `(CH_(2) = Q)` (methanal).
e. (H) is `1^(@)` alcohol with 5C, and GR. contains 3C, so (V) is (ethylene oxide).
f. (H) is `1^(@)` alcohol with 5C, and G.R. contains 4C, so (VI) `(CH_(2) = O)` (methanal or formaldehyde).
