Question

What type of bond is B and H ?

Answer 1

1. Boron is an element of Group 13 in the periodic table.
2. Due to the small size of Boron, the sum of the initial three ionization enthalpies is very high.
3. Due to this it only forms covalent compounds.
4. In the trivalent state, the number of electrons around the central atom in these compounds will only be six.
5. Hence these compounds are then regarded as electron-deficient compounds.
6. They can accept a pair of electrons and are regarded as lewis acids.
