- dichloromethyl vinylsulfideCHCL2-S-CH=CH2 comment very generally on bond length in the molecule. (also point out/ explain unusual or unexpected bond lengths)The bond length of the indicated C-C single bond in hexa-1,3,5-triene is about 146 pm, which is considerably shorter than that in ethane, H3C-CH3. (a) How much shorter is it? Hint: See Figure 14-2, page 685. (b) Which occupied T MOS (obtained in Problem 14.32) help decrease this bond length? (c) If an electron were promoted from the HOMO to the LUMO, would the length of the C-C single bond increase, decrease, or stay roughly the same? Explain. 146 pmUse the following MO diagram for Be2, Be2*, and Be2. Be, Be,* Be, + - 12p 12p | o2s o2s o2s Based on this diagram, Be,* and Be, are both more stable than Be2. Be, is more stable than Be2, and Be2 is more stable than Be. Be,* is more stable than Be2, and Be, is more stable than Be. Be, is more stable than either Be, or Be2.
