The central atom is A. The atoms surrounding A are represented by B. Pick the true statement. 1. It has one lone pair of electrons on A. 2. It has two single bonds and two double bonds. 3. It has linear molecular shape. 4. It must be an anion. 5. It is a polar molecule. 6. It exhibits resonance. 7. It is sp 3 hybridized. 004 10.0 points Carbon has a valence of four in nearly all of its compounds and can form chains and rings of C atoms. Consider the allene structure. C C H H C H H a b c What hybridizations would you expect for the carbon atoms identified by a, b, and c, respectively?...
