0.15 gm (organic compounds) $\underset{}{\overset{AgN{O}_3}{\to }}AgBr\left(s\right)$

$\downarrow$                                                                    

0.2397 gm

Weight of Br in AgBr = $\left(\frac{80}{188}*0.2397\right)=0.102gm$

% Br in compound = $\frac{0.102*100}{0.15}=68\mathrm{\%}$

Due to the larger acid dissociation constant (Ka) sulphuric acid acts as an acid and HNO₃ acts as a base.

Kindly consider the following figure

Due to the absence of acidic hydrogen in But – 2-yne, metallic sodium does not react with this.

Orlon fibres are the polymer of acrylonitrile

In metamers, distribution of alkyl groups are changed with respect to polyvalent functional groups.

ln $Cul,C{u}^{+}has3d^{10}4s^0,\left[n=0and\mu =0BM\right]$

ln   $\left[Cu{\left(N{H}_3\right)}_4\right]C{l}_2,C{u}^{++}has3d^{9}4s^0\left[n=1and\mu =1.73BM\right]$

$ln{O}_2^{-}\&{O_2}^{+}$ only one electron is unpaired in anti bonding MO,

Hence [n = 1 and $\mu$ = 1.73 BM]
