Question

Each carbon in carbon suboxide (C₃O₂) is
(a) sp² - hybridized
(b) sp³ - hybridized
(c) sp - hybridized
(d) sp² - hybridized but linked with one co-ordinate bond

Answer 1

I think , c is right.

Answer 2

Answer to your question is

O=C=C=C=O

C3O2 or “carbon suboxide” is an interesting compound with four cumulative double bonds, making it a . It’s often used to improve dye quality in various furs and fabrics.

The two oxygen atoms will each carry an oxidation number of -2 by default (General rule). The two inner carbon atoms will have oxidation numbers of +2 and the central carbon is neutral with an oxidation of 0. This neutralizes the sum of the oxidation numbers (the total oxidation number of any compound must be equal to 0).

C)sp - hybridized
