Boron
Boron - Boron (B) is the first member of group 13 of the periodic table and is the only non-metal of this group. It has an electronic configuration of 1s 2 2s 2 2p 1 with only three electrons in its valence shell. Dissimilarities of boron with other elements of this gr..
Compounds of Boron
Boron hydrides (or boranes) - The hydrides of boron are known by a general name borane. These boranes are gaseous substances at room temperature. The general formulae of the two important series of boranes are B n H n + 4 and B n H n + 6 . Amongst the well known boron ..

(KNO 2 ), carbon dioxide (CO 2 ) and carbon monoxide (CO). The properties of compounds are absolutely different from the properties of the elements that constitute the compound. For instance, hydrogen is combustible and oxygen is a supporter of combustion. But their product, wat..
Anomalous properties of boron
1. Boron is a non-metal whereas aluminium is a metal. 2. Boron is a bad conductor of electricity whereas aluminium is a good conductor. 3. Boron exists in two forms-crystalline and amorphous. Aluminium is a soft metal and does not exist in different for..
By electrolytic reduction of boron compounds
Boron can be obtained by the electrolysis of fused mixture containing boric anhydride (B 2 O 3 ), magnesium oxide (MgO) and magnesium fluoride at 1100C. The reactions taking place during electrolysis are,..
Hybridisation in Beryllium and Boron compounds
Solution - In NF 3 nitrogen involves sp 3 hybridisation and one position is occupied by a lone pair. Therefore the molecule is pyramidal. But in BF 3 , B involves sp 2 hybridisation having triangular planer geometr..
