In Borax (Na2B4O7.10H2O)\left(N{a}_{2}{B}_{4}{O}_{7} . 10{H}_{2}O\right) if number of sp2s{p}^{2} hybridised B-atoms are X and number of sp3s{p}^{3} hybridised B-atom are Y. What is the value of sum X+YX + Y ?In Borax (N a _ 2 B _ 4 O _ 7 . 10 H _ 2 O) if number of s p ^ 2 hybridised B-atoms are X and number of s p ^ 3

Correct answer

4

Step-by-step solution

In Borax 2-B-atoms are sp2s{p}^{2} and 2-B-atoms are sp3s{p}^{3} hybridised

X=2,Y=2X = 2, Y = 2

X+Y=4X + Y = 4

In Borax (N a _ 2 B _ 4 O _ 7 . 10 H _ 2 O) if number of s p ^ 2 hybridised B-atoms are X and number of s p ^ 3
