Can hydrogen be in between two carbon atoms?

Question

thanx

Answer 1

sure physically, but it can't share electrons with two at once.

So you wont see   CHHC

Answer 2

No, Hydrogen and Helium have the electron configuration of 1s1. They can only fill the 1s orbital to 1s2, with one electron being present in the lone atom and one coming in from another element to fill in the 1s shell. Unlike d block elements, lighter elements don't have the option of accepting extra electrons in energetically favorable ways.

Answer 3

Cannot be because hydrogen can make a single bond not double  

Answer 4

Hydrogen has only one electron to share so it can only interact with one other atom at a time.  There may be some unique and bizarre exceptions, but I can't think of one.  So it would be difficult for a hydrogen atom to bond with two other atoms at a time.  

Answer 5

no

Answer 6

I don't think there are any compounds in which this happens, although hydrogen can lie in between two boron atoms in B2H6, and in Ionic hydrides (e.g. NaH) can be surrounded by six metals.

Answer 7

only in so-called non-classical (hydrogen-bridged) carbocations
