Q. In the compound $N a_{2} [B_{4} O_{5} (O H)_{4}] .8 H_{2} O$ , if the
(i) number of $B — O — B$ bonds is ‘x’
(ii) number of $B — B$ bonds is ‘y ’
(iii) number of $s p^{2}$ hybridized B atoms is ‘z ’
Calculate the value of $x + y + z$

$x = 5, y = 0, z = 2$
$∴ x + y + z = 5 + 0 + 2 = 7$

Q. In the compound Na2​[B4​O5​(OH)4​].8H2​O, if the (i) number of B—O—B bonds is ‘x’ (ii) number of B—B bonds is ‘y ’ (iii) number of sp2 hybridized B atoms is ‘z ’ Calculate the value of x+y+z

x=5,y=0,z=2 ∴x+y+z=5+0+2=7

Q. In the compound $N a_{2} [B_{4} O_{5} (O H)_{4}] .8 H_{2} O$ , if the
(i) number of $B — O — B$ bonds is ‘x’
(ii) number of $B — B$ bonds is ‘y ’
(iii) number of $s p^{2}$ hybridized B atoms is ‘z ’
Calculate the value of $x + y + z$

$x = 5, y = 0, z = 2$
$∴ x + y + z = 5 + 0 + 2 = 7$
