Question

2 electron 3 atom bonds are formed in diborane between hydrogen and boron.
If true enter 1 else enter 0.

Answer 1

Answer 1

A three-center two-electron bond is an electron-deficient chemical bond where three atoms share two electrons. Diborane $B_2{H}_6$ structure containing four terminal and two bridging hydrogen atoms. The model determined by molecular orbital theory indicates that the bonds between boron and the terminal hydrogen atoms are conventional 2-center, 2-electron covalent bonds. The bridging hydrogen atoms provide one electron each. Thus the $B_2{H}_2$ ring is held together by four electrons, an example of 3-center 2-electron bonding. This type of bond is sometimes called a 'banana bond'.
